The quality exceeds all expectations, I recommend to buy.
I bought for a bosch gll 3-80 level, it fit perfectly. I even managed to remove it into the free space of the level case by cutting off the plastic pallet.
Pros
Looks solid, made of sturdy plastic. You can magnetize on metal surfaces, cling to vertical and horizontal pipes or crossbars with a clip.
There is a height adjustment with a microlift within about 8 cm.
Can be screwed onto a tripod to make it easier to adjust the position of the level.
For the price it's a bargain, in my opinion.
