First check-up appointment and AccelDent

Yesterday I had my first check-up appointment, 8 weeks after the first visit. The doctor said that the two cuspids are moving nicely and the spaces are closing. I can see a nearly 2mm shift on the right side, the left one is moving slower. So they activated the left side a bit more to make up for the difference.

I also got my AccelDent. My first impression wasn't very good. When I opened the package I saw a fancy shiny box, way oversized for what it contained. The device itself doesn't seem very sturdy, it has a one-year warranty, but seems like it might not withstand a daily use for two years. But for the amoutn I paid ($580) I expectred someting more sturdy. The worst part of the package is the plug that one is supposed to use to charge the AccelDent. It's so flimsy it doesn't even stay in place when plugged in, I will have to buy one myself to use it. For the first charging before using the device I used my phone charger!
Here is a picture of the device:

 

 I was still skeptical while running it. It seemed to change the vibration frequency, I am not sure if that was intentional or not. But after I was done with the 20-minute session I felt the pain in the teeth (especially the molars) greatly reduced! So maybe the AccelDent is actually doing something!
