5/5
The product is of very good quality. and works very well.

5/5
I don't have the way to check the specs, but it seems to work as the specs written. The product is for industrial use because there are no on/off switch and no plug. But it's not hard to set up to even me who is not familiar with this kind of electricity items. I'm really satisfied with the product! Thank you so much!

Works well, has a turning gear system that allows you to set the desired opening. Easy to install, easy to use, good quality.

5/5
It functions well and appears quite robust.
The knob is a little loose to turn and so
making fine adjustments requires sensitive
movements.
