ROBBX
Parking disc with ice scraper

The parking disc with ice scraper from ROBBX made a very good impression in our test. In the colour blue and measuring 15.5 x 12 x 0.7 cm, the multifunctional parking disc is STVZO approved throughout the EU.
The parking disc is made of sturdy plastic and is well made. The front is blue, with the parking time display in the centre. The arrival time can be set with a wheel on the top of the display. The shopping trolley chip and the tread depth gaugeare located on the back of the parking disc. The edges on the side of the parking disc are hard enough to scrape ice off car windows in winter. The shopping trolley clip fits well into standard shopping trolleys.
The permissible minimum tread depths for winter and summer tyres are also indicated.

Advantages

STVZO approval
✅ incl. ice scraper
✅ Shopping trolley chip always to hand
Tread depth gauge with markings for minimum tread depths

Disadvantages

❌ No significant disadvantages

The first impression

The packaging and labelling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. Of course, adequate protection of the product must also be ensured.

shrink-wrapped parking disc

The ROBBX parking disc with ice scraperwas delivered together with other products in a single shipping box. The shipping box 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 filler. The product packaging was undamaged and in perfect condition. Both the shipping carton and the product packaging were easy to open without tools. The parking disc was shrink-wrapped in a transparent plastic film. The film provides additional protection against soiling and damage during transport. As the product packaging is sufficiently robust, we believe that the film could have been dispensed with. Overall, the set is well protected in the packaging and, apart from the film around the parking disc, no unnecessary packaging material was used.

After unpacking

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 ROBBX set consists of a parking disc with shopping trolley clip and a tread depth gauge. The result is a well-rounded set.
Instructions for use are not included. However, as the parking disc is self-explanatory, this is not necessary.
Contact details are provided on the product packaging. These include the company name, the address and an
e-mail address. Unfortunately, there is no telephone number.

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?

Recesses

The parking disc is made of sturdy plastic and is well made. The front is blue, with the parking time display in the centre. The arrival time can be set on the top of the display using a wheel. There are edges on the sides for scraping ice and a black rubber lip on the underside for wiping windows.
The shopping trolley chip and the tread depth gauge are located on the back of the parking disc. The parking disc has corresponding recesses into which the two parts are clamped. This clamping mechanism makes it easy to remove the shopping trolley clip and the tread depth gauge from the parking disc and attach them again. The tread depth gauge has a sliding mechanism with which the measuring tip can be inserted into the tyre tread. The rear end of the slider then shows the tread depth on a millimetre scale. The permissible minimum tread depths for winter and summer tyres are also marked.

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.

*The maximum score is 100 points

In the colour blue and measuring 15.5 x 12 x 0.7 cm, the multifunctional parking disc is STVZO approved throughout the EU.
The parking disc can be used as intended. Removing the disc works well with the rubber lip. This is particularly practical for exterior mirrors, as the short side of the parking disc is not too large. The edges on the side of the parking disc are also sufficiently hard to scrape ice off car windows in winter.
The shopping trolley chip fits well into standard shopping trolleys. The tread gauge is also very easy to use. After just a few seconds, the tyre tread depth can be read with millimetre precision. The minimum tread depth markings are practical for avoiding fines or passing the TÜV test. However, it would be desirable to indicate that significantly higher tread depths are required for safe road use.

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. There are often complaints that the shopping trolley chip does not fit into the trolley, but we cannot confirm this. Many customers like the robust material and durability. In our practical test, we were able to confirm that the quality of this parking disc was good.

Prices of up to €6.99 are charged on the Internet for equivalent products. Very inexpensive products are available for as little as €2.49. The ROBBX parking disc is currently priced at €3.99, which puts it in the middle price segment. The price ratio is good for the quality and scope of services you get.
