I received it, but impossible to max out 2 of the 5 rods because on one of the boards, the holes are drilled just "below" ... damage to image quality "Made in Jura".
On the other hand, the rings are not rigid and heavy enough to obtain a correct aiming.
I sent a message to the seller with photo support, and I expect to see the solution he proposes to make games "usable".
Stay tuned.
