None of them are bad when it comes to fit but the Airlinks 101 werent as secure in my ears as these or the Isports. At least as durable as the OEM product, its actually a bit easier to use and adjust, being much closer to a Countryman style, form and fit, but at a fraction of the cost. I do still have hair on the pick when Im detangling after a good rinse BUT it is not as much (like a fraction) as when Id used a plastic afro pick. I like the flutter sleeves because my arms are heavy so covering part of them is a personal preference for all of my nightwear. It’s hard to order online. He said just give it away. Okay, setup was relatively easy. Anyway it;s not that difficult to figure it out but you may be wasting time to screw/unscrew couple of times. This is working for me I cant speak on anyone else everyone body is different but my stomach has gotten smaller. I highly recommend these anyway due to the comfort, style, and they last a reasonable amount of time.
