Cheap collars that work great. The open design is awesome and the hold with both levers down is strong. I usually do 1 because it's strong enough to keep things in place. They fit on axle collars which is a big plus. Only complaint is I wish the magnets were a little big stronger

Works like it should. Perfect for an accessory upright

Great piece to have in the gym! Lateral raises work well because you have the ability to load the beginning. I have extra handles from my Giant open trap bar and attached it to the end of the Dragonfly with M10 double end threaded studs. With the extra length both front and lateral raises feel even better. The quality is ok. My unit had a little bit of unfinished metal inside of the arms so a mag pin can't sit in there, but Fringe has excellent customer service and they made it right.

I have the supinated medium knock off and it works really well. Feels great and have no quality issues. I have not tried the actual MAGs though

I love how they give me 2.5 jumps between dumbbells now and with heavier ones, I can buy in increments of 10 instead 5. They might be expensive at first, but it's cheaper to buy this than increments of 5 dumbbells
