Harley Benton InTune Tension Capo

As the title suggests, string bending doesn't work with this capo.
I've used Dunlop trigger capos for 20 years and haven't noticed anything different when I use them - I just clamp it and play how I play. With this one, I go out of tune -looks like the rubber/silicone? part that makes contact with the strings is maybe too soft, and the strings slip and go out of tune when I bend. Tightening the spring helps a little, but then you don't get the benefits of clamping the strings with just enough tension to get good tone and retain intonation.
If you don't bend then it's fine. If the capo was straight it would have been great for classical guitars with flat fretboards, but it does have a slight radius so you can't use it on your classical. I think they should consider making a flat model for classical /nylon string guitars, I'd buy it.
The mechanism that tightens the spring seems like the thing that might go first, otherwise built seems solid, the finish and feel are very nice, and it does have a decent weight to it.
As much as I like Harley Benton, I'm not sure I'd recommend this one.

It feels sturdy, and the adjustable tension is a good idea. However, the physical design of the handle is a bit of a miss. It keeps sliding around in my hand. The ideal point to squeeze the capo open would be at the tips of the handle, but it's so slippery and awkwardly shaped, that it keeps slipping up and I'm always squeezing near the hinge, which is the worst place to be squeezing. Really big oversight on the design, given that there's one point of interface it's supposed to be handling, and it can't do it well. So, awkward in hand, but once you get it in its place, it works just fine. I don't know. There are probably better alternatives.
