yes i have three, two work perfectly the other is not broken just Temperamental! the two working ones are perfect (for me). not amazingly sensitive but good enough for me! they don't boast a huge amount of features just volume and tone control. The 'Temperamental' alarm is like that because it got droped in a lake! It still works sometimes but other times it is dead to the world! i am slighly concerned about the waterproofing so i have sealed the join with gaffer tape to keep me in a secure state of mind but for ?19 a bargin! ..........Although i reckon for a little bit extra ?3 you could get the fox micron for ?22. doesn't have any features except volume but is reliable most of my friends use it and it takes a beating and still works!
