And even super efficient! Well the thing that disappoints me a bit is that there is a lot of plastic product. Including joysticks which is operated by hand. But that appears to be good for carpentry, cabinet making, DIY ... You just do not throw greenhouse attached like a big nag, soil, hastily. I could use them to mount a bookcase and frankly they helped me (I took 2!). The clamps leave no traces, no need to put cardboard or cloth to protect your wood. The investment has the rubbery air.
For me, it fulfills its mission and I highly recommend it!
