speedy delivery

Fast shipping and sincere follow up emails.

I use it for myself, I’m 66yrs 🧠 maintenance

Service and shipping were very good.

Prompt delivery

I like the light, it works, looks nice, is easy to use and was delivered in the time stated.

Clear, easy way to purchase items. Relatively quick delivery to Europe. Good communication.

After using the light for only 10 days for 2x 20 minutes each day it is too soon to notice any neurological changes.

Incredibly helpful and service oriented!

Quick shipping, easy. Only wish the power cord wasn’t black and ugly.

Good products with very good customer service.
