Review on WER Silicone Mug Wraps for Sublimation Mugs: 11OZ 3D Silicone Mug Wrap + Oven-Safe Press, 2 PCS by Gelin Battle

I've tried at least 8 cups with these wrappers so far (I got two). I had problems with the first wrapper so I used the second one and ended up having problems with that too. Despite the solid and tight fit, the results are very inconsistent. I use a Black and Decker - 425 convection oven for 12 minutes. The packs close well, but it depends on whether the cups are pressed well or not. See photos. Each photo shows both sides of the mug. One side will look good - sharp, clear, bright, while the other side is faded, fuzzy, and slightly fuzzy. Very frustrating.
