I bought this specifically for fast charging my Galaxy S7 Edge which it does not do. The Dual Ports will be nice for charging other devices maybe?

This screen protector is great where privacy is concerned.... but it already has a crack going from the bottom to nearly the top it. I have only had this screen protector on my phone since Monday and I am super OCD about my phone and not dropping it etc. I'll still order screen protectors from Amazon, but probably a different brand.

The rope light arrived with one 3ft segment operating intermittently -- it would go on/off seemingly unpredictably. I finally narrowed it down to one small section. If I put a 180 degree bend in the rope and use a twist tie to hold it in place, it works. This is OK in my application, and too much trouble would be required to replace the rope, so I'll keep it. Looks like poor quality control.
Intermittent operation -- lack of Quality Control??
