Absolute garbage..!!
Both threads where it comes in half and the bottom one for the batteries have both worn out within a few months and haven't even used it much so the whole thing just falls apart. The one i purchased before lasted me for about 2 years before it went faulty. Would stay well away from this one it was cheap and nasty. Suppose that's what you get for £12.

Doesn’t go 30km
Overall this is a brilliant bit of kit.However it doesn’t even go 6km as described but I was expecting that anyway.Would recommend if your only wanting to prove shorter distances. I couldn’t give an actual measurement on how far this goes as I’ve only used it for opposite end of exchanges.
