For many of their items, they are exceptional value. Some stuff is garbage, though. The pop-up tents are awesome! There - I said it! "I like pop-up tents". Feel like I should be at some sort of therapy group now saying 'My name is MikeyP and I ... choke ... quite like pop-up tents ... sob'
A lot of the basic clothing is very good - the softshell winter walking/climbing trousers are fantastic, waterproofs are ok, camping basics are ok. Things like sleeping bags, rucksacks and inflatable mats are generally a step up from those you get from Tesco (Ultralite down sleeping bag excepted, of course) but mainly not as good as the brand names. The bike repair stands and a lot of the cycling kit is pretty good. They do some really good own-brand climbing stuff like rope bags and some of the clothing.
I always pop in and have a look if I'm passing The Fort in Glasgow, it's nice for a wander even if you don't buy anything.
