I've just ordered another 2 from bonbon pebbles on ebay. Been using him for 3 or 4 years now. They take a couple of weeks to get here but i gotta say..........I ain't ever had a problem with them yet. Always been entirely reliable and answers any questions i have as soon as he can get round to it. They still work out at £145 each,including delivery( i ordered 2) I must admit that although cheapo chines backpack has lasted one day so far..........I am so worried about leaving it on charge overnight. I feel totally fleeced but going from the lack of replies...........I guess there's nothing i can do RE returning it. I just hope it packs up sooner rather than later,then i will have grounds to complain. If it don't pack up....well at least it seved it's purpose. Who knows......it "may" turn out to be a faithful workhorse..........doubt it,but it might.
