The first impression

Packaging and contents

Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Verpackung der Fensterbilder
Packaging of the window pictures

The product protection of the window pictures from Milula Studios was impressive, as the product arrived without scratches or soiling. The packaging showed a conscious avoidance of unnecessary packaging waste, although the use of plastic film was noticeable, which could be optimized in terms of sustainability. The contents of the pack were impressive with a generous 200 window pictures on 9 sheets, allowing for a wide variety of designs. A small set of instructions can be found on the back of the packaging. The product proved to be largely self-explanatory to use.
Product protection and environmentally friendly packaging characterize the first impression, while the generous package contents open up many design possibilities.

Die neun Fensterbilder-Bögen
The nine window picture sheets

The window pictures from Milula Studios present themselves at first glance with an appealing and simple design. The high-quality workmanship indicates a long service life. The high stability of the window pictures ensures that they are securely attached. Unfortunately, there is no information on the sustainability of the product, but the residue-free removal of the stickers suggests that attention was paid to ecological aspects during application.
The simple and attractive design of the window stickers is complemented by high-quality workmanship and high stability . The lack of information on sustainability could be optimized by transparency on the part of the manufacturer, but the residue-free removability leaves a positive impression.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test has the highest relevance and therefore weighting. 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

Installation proved to be user-friendly and could also be carried out alone. The self-adhesive window stickers showed excellent adhesion, which was maintained over the entire test period. A clear advantage is the reusability of the stickers, which confirms the functionality of the product as a window embellishment element.
The versatile application options in different rooms make the window decals flexible to use, although it should be noted that they are not suitable for damp rooms. The availability in different colors and shapes allows the consumer to meet his personal taste and the desired room aesthetics.
In summary, it can be said that the Milula Studios window picture set fulfills the manufacturer’s advertising promises and is therefore a recommended option for decorative window design .

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine 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 look at the consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioVery good in the lower price segment90 points
Rating cut4.6 out of 5.0 on Amazon80 points
Total85 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.6 stars. The ease with which the flakes and stars can be attached to the window is highlighted positively, especially by parents who report their children’s enjoyment of the winter decorations. The large selection of motifs and the simple disassembly according to the instructions lead to a clear recommendation to buy.
However, there are a few customer reviews that point out that the adhesion of the stickers does not remain stable over a longer period of time. Another point of criticism is the size of the stickers, which may not be sufficient for larger windows. In our practical tests, we were able to confirm the positive aspects.

Prices of up to €19 are charged on the Internet for equivalent products. Very inexpensive products, on the other hand, are available for as little as €6. This puts Milula Studios’ window pictures in the middle price segment with a current price of €6.99. Consequently, the price ratio is very good for the quality and scope of services you receive.
