Aye that would be me.... My review is hereif you do a search on here someone tested a load of these and posted results a few months back. Hope it helps.
Ok cheers i will have a look at that.Try a microclimate advanced heating system, it'll set you back 100 squid but well worth it. Has a built in stat and would heat a 6x2x2 no probs. I've got one in my 7 x 6.5 x 3 viv. They come in different wattages, I recommend the 500 watt, Takes less effort to heat viv and the difference in price is marginal.
