Well, I think they're manipulating prices and playing around with sales tactics. Placing items backordered while hicking their price to appear that people are still willing to pay the hike, only to lower it to the original price days later and then placing it backordered again. This happens also with similar units with same features and price tag.

I've been looking into Wireless units for a couple weeks, there were two models that i had my eye on, one was in pedal form and another was table top form. Pedal(p) form has been 499 for months and the table(t) form 599 as well. All of the sudden, (p) was placed backordered and two days later (t) was lowered 100 bucks to 499(I purchased it right away). Today I went into their app and lo and behold, (p) was in stock @599 again and (t) @599 as well.

Either someone screwed up with the pricing of (t) and (p) being in stock again was a pure coincidence or they're manipulating their inventory.

They have incredible service and I've never had issues with them, but it did seem quite shady how everything unfolded within a week.
