We got most of ours from B&M. Find most of them are really quite good but some sets we have bought have been complete duds (the dragonflies were the worst!). Especially like the flower ones we got for DD's bedroom at home. In the summer they light up for ages when it sunny and they manage to light up most days in the winter, except for days when it's rained the whole day.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
