Brought this product to keep my phone topped up whilst out of the house for extended periods of time such as day trips away or camping. This product lived up to expectations and performs well charging my phone to full in a short period.
I was expecting something that would at least be comfortable to wear but I didn't find that with this product. I couldn't seem to forget it was in my mouth which made it impossible to sleep with. On the plus side the postage was quick though!
The build quality I am a bit skeptical about after the first one I received failing to work and falling apart - however GreyMobiles quickly and happily handled this and dispatched a new one within two days and the product works well! It does what it says and for a very reasonable price. I've been using this product for two weeks now without any hiccups!
