Firstly: I was impressed with the quick delivery. Within 3 working days I had received my vest. That's Service.
It was securely packaged. The instructions within are simple and easy to follow making this a great gift idea.
Once I charged the battery and a quick test. I was happy with purchase.
The next bike ride I had it on under my jacket. The vest is light, comfortable and fitted well, especially under my riding jacket.
I had it on all day, and it worked better than I had ever imagined. I could get heat onto a sore spot on my back with a simple movement whilst being comfortable on the bike. My back was in heaven. I wish I had bought this year's ago.
Secondly: I recommend this jacket. It's light comfortable easy to use and fits well as a vest or under my riding jacket.
