Initially, I ordered a Large mask from Best Weston CPAP and he pulled a Bait & Switch and sent me a Medium mask. IMO, he was nasty and a schoolyard bully. Totally uncool for a 59 year old dude. I then talked to other customers, and I understood that he appears to sells used stuff or parts of used stuff as new on sites like Amazon who don't seem bothered by his antics, and are possibly protedting him. I just wanted to expose him and caution other customers, especially that he has no website, and he doesn't publish any personal information.
