These keychains are very good. The bad reviews I see are mostly small errors that I made myself. One of the worst complaints is that the back glitter melts off when pulling heat tape. I did this on one and realized that I need to wait for them to cool. This is also very important when it comes to tape accidently getting on the front. One of them I pulled off the mat but left the heat tape on for it to cool and it wrapped around the front. For most things, this wouldn't matter since it is no longer actively heating and transfering ink, but because these keychains are made of a material that holds heat longer, the ink from the image transferred onto the tape while cooling and I ended up with a white spot.Be sure to let these cool completely before removing tape or anything. That is very very important. The image sublimated well and if you wrap the image along the side just a little, you can usually get the area where some people said it won't sublimate.Another thing you can do for the side, is wrap the image around and when it cools, take a small handheld heat press along the sides to get that pesky ring of white.Overall, good product with a small learning curve. Will get again
