DX Fitness
Door strap for fitness bands

In our test, the door strap for fitness bands from DX Fitness made a very good impression. As well as being easy to install, the product also offers outstanding quality. In addition, the door strap is height-adjustable and can be customised for any exercise. Nevertheless, a larger selection of fitness bands would have been desirable in order to have the right weight or resistance for every exercise.

Advantages

✅ Outstanding quality
✅ Quick installation
✅ Simple height adjustment

Disadvantages

❌ Small selection of hinges
❌ Interferes with door when not in use

The first impression

The packaging and labelling

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

The door trainer from DX Fitness arrived in the classic Amazon box. The contents were packed in an extra box, which is visually very nicely designed. However, the box had a few signs of use. Despite this, the product was well protected and arrived without any damage. It should also be emphasised that no plastic was used in the packaging of the door trainer. As only cardboard was used, the packaging is very sustainable and can be reused. The packaging gives the door trainer a very good first impression.

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?

After unpacking, you first find the door trainer in the carrying bag provided, which is really great for travelling. It comes with clear instructions, a QR code to open the explanatory videos and a thank you card. Inside the carrier bag you will find 2 different fitness bands, 2 handles, 2 foot straps and the door holder. With the instructions and the great video, the door holder is very easy to set up. You can then start exercising straight away. The door trainer makes an excellent first impression.

The first time in your hand

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?

CriterionRemarkScore achieved*
Visual appearanceMinimalist design, fits into any home100 points

Total91 points
Weighting: 20%
*The maximum score is 100 points

The colour selection of the black belt and the red or green strap is well chosen, so the door trainer does not immediately catch the eye and fits into any home. The door strap, fitness strap and handles are excellently manufactured and have no negative conspicuous features, which is why the product appears extremely stable. In our test, we could not find the maximum of the latex bands, as they withstood every stretch. The only negative point that stands out is that a fastening for the fitness band when not in use would have been desirable. The strap gets in the way when opening and closing the door. Ultimately, however, the door trainer makes a very good impression.

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.

CriterionRemarkScore achieved*
EffectivenessVery effective training for at home100 points
Height adjustabilityEasy adjustability with double buckle100 points
DurabilityNo signs of wear after many training sessions100 points
VariabilityOnly two different fitness bands75 points
Total94 points
Weighting: 30%
*The maximum score is 100 points

With the door trainer you can do really effective training at home. Thanks to many explanatory videos online, all possible muscle groups can be trained with the door trainer. The perfect height adjustability, which can be easily adjusted with a double buckle, also contributes to this. This allows the fitness bands to be used from different angles. Unfortunately, there are only two different fitness bands, which means that no major weight differences can be made. After many training sessions, there are still no signs of wear. The door trainer completely fulfils its purpose and offers excellent home training.

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.

CriterionRemarkScore achieved*
Price / performance ratioUpper price range but excellent performance90 points
Rating cut4.3 out of 5.0 on Amazon65 points
Total78 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.3 stars. The fact that there are only two training bands is often criticised. Many customers like the fact that the door trainer is excellently made. In our practical test, we were able to confirm that the workmanship was very good and that the selection of fitness bands was not so good.

Prices of up to €50 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €15. The door belt for fitness bands from DX Fitness is currently priced at €49.99, which puts it in the upper price segment. The price ratio is reasonable for the quality and scope of services you get.
