I doubt I will find this in any Boots near me as they only seem to have tat on offer .
The older models are far better than the newer ones but for a tenner it's great value !!!
I've had one of these (controller is slightly different, so could be different generation) for the past couple of years. It's been superb, super fast warm up, gets really warm on the fast start settng, lots of heat settings, even heat across the underblanket. My one complaint is that although the 1-5 heat settings have auto shutoff options (1 or 9 hours), unless I've missed something, on the version I have there's no auto shutdown on the fast warm up setting. So effectively, you can put it on fast warm up, which is also the hottest setting, fall asleep with it on and it'll stay on until you manually turn it off.
Used this (older model from Amazon) for the last 3 years almost every night One the best purchases I've made.
Massive problem with controllers that stop working after a while. I had the same problem on 3 of their products. Google this and you will see massive complaints especially on amazon. It's a great blanket without that problem, heats up very fast.
