ROBBX
Velcro licence plate holder

The Velcro licence plate holder with parking disc from ROBBX made a very good impression overall in our test. The set consists of two number plate holders, the corresponding mounting material, a microfibre cloth and a profile depth gauge. The licence plate holders are actually frameless, as the entire mounting mechanism is concealed on the back. This gives the vehicle a particularly elegant look. All components of the set were also convincing in the practical test. Although the installation effort is higher compared to a conventional screwed licence plate holder, both the adhesive and the Velcro connection hold very well. The microfibre cloth and the tread depth gauge also proved to be useful gadgets in the test.

Advantages

✅ Good hold of the licence plate
✅ Enhancement of the vehicle appearance
✅ Mounting material included
✅ Can also be fitted with curvature
✅ Microfibre cloth and tread depth gauge

Disadvantages

❌ Increased assembly effort
❌ No indication of a telephone number

The first impression

Velcro licence plate holder in the product packaging

The Velcro licence plate holders from ROBBX were delivered together with other products in a single shipping box. The shipping carton was compact and the individual products had little room to move around. The remaining space in the shipping carton was therefore filled with recycled paper padding. The shipping box contained the licence plate holders with accessories in the product packaging. The product packaging was undamaged and in perfect condition. Both the shipping carton and the product packaging were easy to open without tools.
The product packaging is an elongated cardboard box in an attractive black and red design with a vehicle motif. It contained the two number plate holders, instructions for use, the microfibre cloth, length stickers and a zip bag with a tread depth gauge, removal squeegee and cleaning cloths. The licence plate holders have been folded in the middle to enable compact product packaging. Overall, the set is well protected in the packaging and no unnecessary packaging material has been used.

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The set consists of two licence plate holders, each consisting of an adhesive hook tape and a loop tape, mounting aids, a microfibre cloth and a profile knife. The mounting aids include four cleaning cloths and four length stickers, which can be used to adapt the licence plate holders to shorter licence plates, as well as a disassembly squeegee, which can be used to remove the licence plates from the holder. The result is a well-rounded set for anyone who has bought a new vehicle or wants to refurbish their old one.
The enclosed instructions contain a discount code for your next purchase at ROBBX and installation instructions. It explains in five steps how to fit the licence plate holder to the vehicle and how to insert and remove the licence plates. The text is written in German, very detailed and easy to understand. The installation steps are also illustrated. Please contact us if you have any queries. There are no instructions for the other components of the set. However, as these are self-explanatory, this is not necessary.
Contact details are provided on the product packaging. These include the company name, address, name of the managing director and an e-mail address. The e-mail address can also be scanned using a printed QR code. Unfortunately, there is no telephone number.

Close-up of the Velcro surfaces, the microfibre cloth and the tread depth gauge

The licence plate holders are in two parts and are made of black hook and loop tape. Each licence plate holder therefore consists of a loop tape and a hook tape. The front of both tapes is fully coated with the respective hook and loop material. The adhesive surface is also fully covered on the back. When delivered, there is still a protective layer on the adhesive surface, which is removed for installation. The strips measure 49.5 cm by 9.5 cm. As with car licence plates, the corners of the strips are rounded so that they do not protrude after installation. A licence plate holder consisting of loop tape and hook tape weighs 69 g with protective film.
The length stickers consist of a printed front side and a removable back side, under which there is an adhesive surface. The front is printed with various cut lines labelled with the measured length of the licence plate. As this does not correspond to the required length of the Velcro tape, this is a practical aid. The cut lengths are graduated in 2 cm increments and are between 50 cm and 34 cm.
The cleaning cloths are alcohol-based cleaning cloths with an alcohol content of 70 %. The size is 20 cm by 15 cm. The disassembly squeegee is made of black plastic and is 13.5 cm long. It is easy to bend by hand, but makes a stable impression. There is an eyelet at the end of the handle for hanging it up.
The microfibre cloth is dark grey with a black edge. The brand name ROBBX is embroidered in the bottom left-hand corner. The cloth measures 25 cm by 25 cm and is very thick. Accordingly, the surface feels fluffy. The tread depth gauge is made of white and beige plastic. It has a sliding mechanism with which the measuring tip can be inserted into the tyre tread. Unfortunately, the slider is difficult to operate. The rear end of the slider then shows the tread depth on a millimetre scale. In addition, the permissible minimum tread depths for winter and summer tyres as well as a recommendation for the minimum tread depth for summer tyres are indicated.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

We carry out our practical test on the rear bumper of a standard compact car . First, we remove the old licence plate holder. This is attached to the plastic of the bumper with four screws and can be quickly removed. The Velcro strips are attached to the rear bumper and the licence plate using an adhesive bond. Adhesive bonds can transmit very high forces, but require appropriate handling. For this reason, we adhere precisely to the instructions for use during installation.
Installation is carried out in several steps. If necessary, the Velcro strips must first be shortened to the correct length. Our test licence plate has a length of 52 cm and thus corresponds to the standard dimensions of European vehicle licence plates. Shortening is therefore not necessary in our case. The next step is to clean the back of the licence plate and the bumper. The cleaning cloths and the microfibre cloth help here.
The Velcro strips are then attached to the bumper and the licence plate. It is important to ensure that the bumper has a continuous surface in the area of the Velcro strip. For example, it is not possible to fit the Velcro to the grille of a radiator grille.
As the Velcro strips are slightly smaller than the licence plate itself, it is not necessary to position them with millimetre precision. In our test, we used the holes in the bumper into which the old licence plate holder was screwed as a guide for positioning . It is important to ensure that the adhesive tapes are applied with sufficient precision in the first step, as it is not possible to remove them again due to the high adhesive strength of the glue.
The licence plate can now be attached to the bumper. The Velcro tape is about one centimetre smaller than the number plate in each direction. This difference can be used for fine alignment by placing the loop tape and the Velcro tape slightly offset on top of each other. If necessary, the licence plate can be removed and reattached using the removal tool.
Overall, the installation is easy to carry out, even for users with no manual skills, thanks to the good description. However, the cleaning and the triple positioning (tape on the vehicle, tape on the licence plate, licence plate on the vehicle) increase the installation effort compared to screw-on licence plates. The licence plate holder is also suitable for mounting on any rounded bumpers. The limit here is not the licence plate holder, but the flexibility of the licence plate.
After drying, the licence plate adheres firmly to the vehicle and there is no risk of it coming off while driving. The look is particularly impressive. In contrast to many alternative solutions, the Velcro licence plate holder is actually frameless, as the entire holding mechanism is concealed behind the licence plate.
The microfibre cloth impresses with its thick material. Not only can it be used to wipe off dust, it also reliably absorbs liquids. The tread depth gauge is also very easy to use. After just a few seconds, the tread depth can be read with millimetre precision. The minimum tread depth markings are practical for avoiding fines or passing the TÜV test. There is also an indication of the recommended tread depth for safe participation in road traffic.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also analyse consumer reviews and check whether the critical and positive reviews are actually justified.

*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.6 stars. One common complaint is that the licence plate holder comes off after a while. Many customers like the fact that the adhesive bond holds very well after installation and the excellent appearance. In our practical test, we were able to confirm the successful appearance and the good hold of the adhesive bond after fitting.

Prices of up to €22.29 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €8.46. The Velcro licence plate holder from ROBBX is currently in the upper price segment with a price of €19.99. The price ratio is reasonable for the quality and scope of services offered.
