I bought the old version of this Lux Spa Laser secondhand (from a chap who posted on here) in November and have been using it since the end of November (without any high dose clinic treatment). No benefits to my tinnitus yet. I sometimes think my hearing might be slightly better, but nothing conclusive. Will not get an audiogram until my next ENT appointment.
Before buying this I spent a week or two experimenting with a cheap 650nm 50mW laser unit. I didn't feel too confident with the effectiveness of how I was pointing this at my head, and wanted the 'in ear' model so I knew the light was going to the right place. I am planning to make an 'in ear' version of my own soon with a bit more power than the 30mW one (keep putting this project off but will get there).
I think from memory Hansi Cross got good results with his MLS/Lux Spa laser, and then went for clinic treatment later. You could check his blog on it for details.

Personally, I suspect that I need more power and will be looking to sell my unit soon. Hope this helps.
