Climbing Technology - Click Up Kit + - Belay device

Great device, very safe. Top-rope mode is already locked, just take in slack.

Lead mode is harder to use, especially with thick ropes. Pay out slack too fast and it will overcome the spring tension and jump into locked top-rope mode. 9.8mm rope works well but can still accidently lock up when paying out slack, 9.2mm rope was significantly easier to pay out slack without accidently locking, but still requires good technique.

A featherweight climber on 9.8mm rope is hard to lower (in general, but especially through this device) since the device has a lot of friction. On 10.2mm gym top-ropes they may have to twerk a bit for their freedom if they want to actually descend.

I have been using this for a few weeks now after years of using the original click-up and have concluded the original is better in almost every way.
The new design and colours are much more aesthetically pleasing and the new grip is nicer to hold than the original metal plate.
The anti-V technology is a small metal plate that pushes the rope to the locking position with much less force loading it, I tested this(safely) and it will lock even if you are not holding the dead rope.
The redesign for a better range of rope width is great as thicker static ropes were sometimes a problem with the first click up.
The problem with this anti-V plate is that it causes constant locking of the device when paying out slack unless you are simultaneously feeding rope in and out from above and below at a steady speed. Any slight acceleration in the rate you pay slack out will cause the device to lock, as will even light resistance on either end of the rope.
Overall I have to give a poor score in the review as nice as most of the new features are, lead belaying is more difficult with this than the easy to use click-up.

Very good for top-rope belaying, though lowering is sometimes a little difficult. However, the new design means whenever lead belaying it is very difficult for the device to not accidentally lock when lead-belaying.
I will be buying a gri gri instead

I have used this product only for several times, but I found that the rope-feeding is not as smooth as that of the previous model, mainly because of a tiny lid which is intended to be a fool proof. I am considering of somehow removing this part from my device. FYI, I use mammut infinity 9.5 and eternity 9.8.
