Review: Avoid !! - This product worked fine for 2 days . First one broke down followed by the other . Seller only offered a refund of £3.75 ! When challenged, they replied that a full refund would only be issued on me returning the item ( at my expense) to an obscure address in China - and only then after an inspection/test ! Not good enough. They finally offered 50% refund only after I insisted ( and only then to cut my losses). Avoid this seller at all costs .
Review: Not Able to Use at ALL! - Definately Did Not Like the Fact That NO Connection Hole Socket! Badly Made!

### ⭐ Don't waste your money
*by M***E on 3 September 2023*

Worked for 2 days then just stopped working. Lights flash suggesting something was working but no pulsing etc. And don't expect the instructions to be any help, they appear to have been translated into English by a 3 year old.
