Bought one of these in there over a year ago. It's a surprisingly good little tool, nice magnetic end and yes Big Clive is using a similar one in almost every single video. I'm sure he got the screwdriver from Poundland (get it there if you have one near). There's none in our Poundland atm. and I like this colour better as the possibility to buy it online and collect later.
For those who never heard of Big Clive, be prepared to get your mind blown:https://www.youtube.com/user/bigclivedotcom/featured
