I was hesitant at first to use a glass protector because I thought the screen sensitivity would be affected. I couldn't have been more wrong. It was simple to install after watching the video AND there's a lifetime guarantee, and no loss of touch sensitivity. II would definitely recommend this product.

the screen protector and video instructions were excellent. Very happy with entire transaction, Thank you

This is a great ab and core training mat. I can't lay flat on my back to do sit ups or crunches. Due to lower back pain. This mat helps by fitting perfectly in the curve of my spine. I don't get that stiff back pain afterwards anymore. My girls love doing handstands on it. The mat itself is very durable and looks to last for a very long time. It has a picture guide on the back showing different types of situps, crunches, and more. I find that very useful. It's also small enough to store and take up very little room

This ab mat is great for getting full range of motion when doing abdominal exercises. It takes some getting used to if you have never used an ab mat before but that's to be expected. This is sturdy but comfortable and helped me power through my ab workouts comfortably

Very happy with this product. It is strong and durable and doesn't shift around when doing floor exercises. Definitely feel the difference with and without it. Helps the strain on lower back. Have already recommended it to others and will continue to do so.
