So, I got a refund for this as it nearly got stuck...in my partner. The tail which acts as an antane is also there to retrieve the item. It came off when it was trying to come out...which caused a little bit of a concerned five mins.
However it could have been a factory fault, the actual power, range and size are all great. I would recommend and thankfully something i did do that time - put it in a condom. If you do that and the wire goes at least you can use the condom to get it out again!
