The available aggregate rating is split between five-star and one-star ratings, with only a very small number of ratings shown. That spread gives little basis for judging fit, comfort, or durability. The listing's customization and thickness claims may be relevant to a buyer's needs, but the ratings do not establish how well those features perform.

Frequently asked questions

Is this listing for upper teeth, lower teeth, or both?

The title says upper or lower and also calls it a single retainer. Confirm which arch the selected order covers before buying.

What thickness options are listed?

The listing names 1.0mm and 1.5mm options. Confirm how to select a thickness when ordering.

Does it include a home impression kit?

The supplied listing mentions a one-time digital impression but does not specify an impression kit or explain the scanning process. Ask how the impression is obtained and what is included.

Can the same digital profile be used for replacement retainers?

The seller claims a saved digital profile and future replacement access. Confirm the terms and availability with the seller before relying on repeat orders.
