Slightly hard to get together but google translate helped, the frame itself is solid. I added my own q-snap larger bars and it holds tension well when laced, may wrap the bars with paper tape just to decrease the minor slips. Very satisfied.
The product is extremely accurate and very easy to put together. I will however say that the connection pieces are not very tight so the frame will swivel very easily on you and that you may need to tie it to something with tension so that you can rest your hand and arm on it while doing your embroidery. The seller shipped it extremely fast and came to me in a weeks time.
