## Customer Reviews

### ⭐⭐ Gets hot and zipper not the best
*by Y***M on October 11, 2024*

I’m giving this two stars because I like that it’s a unique shape. However, it gets hot which I didn’t expect. Also there are two zippers and one of them is hard to zip up again once you’ve unzipped it. The other thing I don’t like is the cords. It just seems more complicated than it needs to be. Plug one cord into a box then another cord into the box. For the price it could have been constructed better.

### ⭐⭐⭐⭐⭐ DGYAO Helmet
*by A***C on August 23, 2024*

I purchased and used Red Light therapy products from several manufacturers. DGYAO is one of the best. Their customer service is excellent.

### ⭐⭐⭐⭐⭐ Works for me
*by H***A on July 21, 2024*

It works for me to prevent hair loss! Keep use it every day for 20 minutes and I hope you can get my feelings too!
