wrap it up in cotton wool & don't take it out

£95 was a lot of money for me to spend on such a thing. I hoped it would last me years. After 18 months it began to rattle and stopped working. The manufacturer insists it is my fault so they do not have to replace. I never dropped this, it was always looked after and kept in its case in my pocket or bag. It obviously got knocked and that was all it took. 395 down the drain, do not buy this product it needs to be wrapped in cotton wool and put to bed is the best advice I can give regarding this product. Useless for outdoor life.
