I have used this to check all my batteries out. For the money it seems to do the job, although I don't think it is as sturdy as a more expensive model would be, but like the saying says you only get what you pay for!
I received this bracelet and for the money it seems pretty good value. It is actually for a Christmas present and just hope that it fits her properly. She is 8 in December and I will let you know if it is suitable or not for her.
Again bought this as a gift for my aunty but she has decided to also keep this in the house. She has some lovely ornaments in the house but she must think it is good enough to put with her Swarovski and other expensive ornaments.
