I'm happy overall with my tooth whitening kit. It works well and is exactly as advertised.
I've tried to get aligners. My first kit to get impressions wasn't good and needed to be redone. I've attempted to reorder the kit 4 times and it has never arrived despite the page saying my reorder is complete. I've put in a support ticket and received no reply. I've responded to emails asking why I haven't reordered and no one replied. I've sat on hold for 30 minutes and never got to talk to a human. I'm walking away at this point, quite content to have gotten out before I actually got aligners.
