The SYB Clip-on Phone Pouch to Shield Cell Phone EMF is made of very nice material. The size is about 5.25″x2.75″ so not for big phones. I received the product in a great time period. I really like this phone holder the only issue I had come across was I couldn’t use it with my case because it wouldn’t fit and even with the case off it was a tight fit. For an idea to make this better is to make more since for the phone. Other than that gear product to get and use.
