The magnets supplied disappoint unfortunately completely:
The trimming of both sets differs widely. While the motives are nicely placed in a set centrally, almost all designs have slipped by about 2-3mm down in the second set. Some of the app logos are thus unattractive cut from the edge.
The motifs themselves correspond - as already mentioned in another review - not exactly the graphics that you expect from Apple devices. Because you still can clearly bring in conjunction with motives to Apple counterparts, this fact would not bother me. However, some graphics are made really bad. The sunflower is wilted (no joke!), As such is difficult to recognize the camera. The pictures in Amazon do not match with the delivered product.
However, the quality of the print is the main reason why I return the App Magnets. All App logos have a green or brown tinge. The colors are not nearly as strong as seen in the pictures. The logos appear faded and yellowed.
Since I have not unpacked the magnets for return from the blister pack, I can not give any clear statement on the magnetic force. By approximately 0.5-1mm thick cardboard packaging of they however have no magnetic effect.
Overall I am really disappointed with this product, which I had hoped that it loosens up my new whiteboard. Although they are not expensive, they are not worth the price and go so return.
