Not worth the moneyArvosana 2/5
I have been using this for a month and the reason I didn't return it is that verkkokauppa doesn't seem to have anything better.
It's a 60e piece of plastic. It has 2 positions for front and back legs but that is the only adjustment you can make. It is not high enough and not wide enough for me.
The legs have some grip but it can still slide without pushing it much.
