Well, finally took the plunge and bought the Argos model....
Couldn't find a 3 whell model at a couple of local proshops (just 2 wheel and leccys)...
Saw a model in Nevada Bob's for £50 but thought I'd try the Argos one as I've got a couple of weeks to return it, if I didn't like it when I got it out the box....
So for those interested.....
Initial impressions are pretty faviouable. Looks absolutely huge but I think thats more to do with the sotrage area near the handle....
I got an old pull trolley out for comparison and I reckon it's only 10% bigger. A bit loger, but that's down to the front wheel.
The frame is also a lot bigger than a pull trolley, which makes it heaveir although I assue that won;t be an issue as you don't need to tip it when pushing it along.
Back wheels seem to come off quite easily which makes it even smaller for stowing in the car but I'm unsure if you should be taking the rear wheels off each time you use it...
Footbrake seems a bit of a pig to get on and off mind you, although I've not yet tried that with te weight of the bag so I reckon that will make it a lot easier.
All in all, I think it's reasonably decent for the price.... Should be having a round with my Dad next week so will get him to use it - Only a month early but that'll be alright...
