I recently got one skin for Nord 4 (with a metal built) the skin was really easy to apply as my device conducts heat quickly after using apps like AnTuTu so I use it in my benefit but I would suggest using a hair dryer for devices which aren't metallic to get precise results. Customer service is absolutely great, I got my product damaged and it was really expensive custom skin so they provided me a full body skin of over variety for free with only the delivery charges (which is reasonable) but overall please be careful and watch a tutorial and most importantly READ the manual and understand the positioning of skins before applying.
