Has anyone used the Trail Buggies you can get from Halfords? look fine for the price, and on inspection today they have a very similar mount as some of the more expensive Burley trailers i've seen online. quite fancied the single child one they stock. Would like some feedback from people who have actually used them out and about. Guy in the shop let me link it to my bike (GT Avalanche), fitted fine but slightly off centre, Are they supposed to be like that as a safety thing?
