This is a great piece of kit, I’ve only used it for just over a week but I can already feel that it’s making a difference. A bit disappointed with the instructions (or total lack of instructions) but otherwise good. It’s been a bit of trial and error, going through the many phases and then testing the levels within to find a comfortable but challenging setting. It’s early days so far, I will give it another month or so and then review again, so far it’s a thumbs up though 👍
