for some reason the right arm keeps popping off of these. i got them for my husband and he’s broken every pair. and you can’t get the screws out without stripping the head of the screws. it’s like they’re glued in or something.i’ve ordered 2 sets and he’s quickly going through the second set.they’re priced great but not very sturdy.
good price and good product/unfortunately very poor quality. 4 pairs lasted 2 years (average 6 months).screws come loose and frame breaks near the bridge easily.time to try another vendor.
