Any update? I am considering using bracesshop but not sure if they are a good seller.

I made an order this spring. I placed the order on about May 19, received the impression kit from Germany on the 25th. I shipped them to China via USPS for 35 bucks (vs $105 for FedEx or UPS) on June 3, and they received them yesterday, June 14. They say they expect fabrication to be complete within a week. I'll update to let you know how long it does take in the end.

I'll say they have been very responsive by email--there's a total of 17 emails in the thread about my order, and it's all been very timely. He emailed 5 days after my order to see if I had received the impression kit, asked for photo of my impressions to confirm they were good enough to use before I paid to ship them, and added an item on to my order. The impression kit came with about 6 ounces of each kind of mixing material--plenty to make several mistakes with the impressions and try over without running out. My experience has been very satisfactory so far, but I'll let you know if the appliance actually arrives and fits!

My items shipped today, June 21, exactly one week after the lab received my impressions. In the mean time, the seller had noticed that I had selected items in two different colors and emailed to ask I wanted them to match. More good signs.

My impressions were sent to Bracesshop's China lab after elevee's were and are now shipping to me as of June 21st like his are.

@jimbobape, what are "impressions" ? Are they necessary to buy appliances ?

Yes. The same process is used for all dental appliances including braces. It's a cast model of your teeth, so they can build the appliance to fit in your mouth. Mouths and teeth are far too different from each other, and dental appliances too precise, to use a mass made appliance.

My order arrived yesterday, the 26th--five business days to reach my door. The appliance fits well. At first I thought it came without a key to activate it, but it's actually a tiny little handmade tool that fits in a box about 1.5 inches square that was easy to miss, not the plastic handled, jointed thing I was expecting.

The appliance came in a little storage case, and they sent back my impressions and the casts made from them, so I'll easily be able to compare progress. I'm pleased!
