I had a slightly farcical attempt at using my new-ish BetaStick yesterday to take a quickdraw off the first bolt on a route that turned out to be too wet and slimey to climb. I thought I remembered how to do it, but actually checked on my phone and re-watched the little video of Charlie Woodburn showing us how to do it - last video on this page: https://www.betaclimbingdesigns.com/products/sport while we stood at the bottom of the cliff.
The end result of my attempt was not only having a quickdraw stuck on the first bolt, but also now the spare krab AND my rope (jammed round the quickdraw, so couldn't just pull it down!
I actually found that just using the BetaStick's head I could push open the top gate of the QD and managed to nudge it up and off the bolt (thank you keylock clean gates!), so it all worked out in the end, but if you're not trying to remove a quickdraw hanging in space from overhanging rock (like in the video) I'd treat Beta Design's suggested technique with some scepticism. But then again, you might find like I did that there is more ways to skin a cat (or remove a quickdraw) with the BetaStick.
Beyond that, I love my clip stick. The BetaStick Evo is really cleverly and sturdily designed. Not sure why it took me so long to get one - perhaps I didn't value my ankles so much when younger!
