These are well built retainers. I'm constantly having to deal with my glasses not staying in place. Even with silicone nose pads, after having had my nose chiseled down, they still don't stay in place unless I have a good retainer that keeps the frames tight to my face. I was excited when I saw these and was happy to have them come with two pairs of grips for slim and thicker earpieces. The two faults I have with them are that they don't allow for me to get my glasses tight to my face. (the cables are just a bit too long for my head) and the way they adjust is great but the pieces that hold each cable together needs to grip the cable a bit tighter so that they are less likely to slide loose. On last thing is that the smaller grips are grey colored. I would rather have them black to match like the larger grips do so the retainer is less likely to stand out. If these retainers have been the best ones that I've found to wear in more formal situations. I like the fact that they eliminate having a cord hanging on the back of my neck or getting caught on my shirt or jacket collars.

The design of this product is great, I was really excited about the mono line and the particular way the cable adjusts, however, the product is absolutely useless because the smallest adjustment is still too large to fit glasses to my face. Just offer a smaller size Chums c'mon.

My adjustable Orbitor’s broke on a kayak trip and I sent in pictures of the damage and within minutes Morgan at customer service responded and approved my replacement. This is why I will always buy chums. Thank you for all that you do! Grateful Customer.

so I love the design, quick delivery, and adjustable system. unfortunately as a previous poster wrote they do not adjust tightly to my head (note I have a size 7 7/8 hat size, so I got a big NOGGIN!)

as I am using it to hold my dental loupes, I need it tight against my head to make sure I can see clearly, which unfortunately is not possible. good product, but please make a smaller size CHUMS!

My glasses would always fall off after 13-14 pushups. Now my glasses always stay in place and I forget the Adjustable Orbiter is even there, because there is no tail flailing around.

I see that some people want a shorter cord, the problem with this request is that the cord needs to be long enough to easily slip over your head when fully extended. When cinched down all the way, it is true that the cord might not be snug up against the back of my head, but it really doesn't need to be to keep your glasses from falling off. Actually if there was zero wiggle room between the cord and your head, you would then be more aware of its presence. I wouldn't let the cord length prevent you from trying this excellent keeper.
