“The dot was smaller than I expected, but it measured accurately. Now that I've had it in for awhile it's all good. In my third hold, the std 6mm back works great. I love love love the flat backs, totally a game changer. Easy to get in and so comfortable.”
“really good product, my only complaint is that fact you have to spend extra to get different length backs. I feel like it would be good to be able to select what size back I would like with the product”
