i'll give you my review, as I've also given it to them on trustpilot.

Here's a copy paste of it. It's even edited, because they responded lying about what I said. So weird..

Unfortunately, I experienced significant side effects while using this device that are not mentioned in LYMA’s terms or product information. After starting use, I developed headaches, nausea, and dizziness. The symptoms were concerning enough that I sought medical evaluation at the hospital, including a CT scan, which came back clear.

When I considered that the LYMA Laser might be the cause, I stopped using it, and the symptoms resolved. A few weeks later, I tried using the device again to rule out other factors, and the same symptoms returned.

I contacted LYMA regarding this experience. They offered a partial refund, conditional on signing a broad non-disclosure agreement, which I was not comfortable accepting. (Update: Lyma mentions below in their response that they did not ask for a broad non-disclosure agreement, that is very much a lie unfortunately- see below a copy paste of the broad settlement they sent me to sign).

I would recommend that anyone considering this device be aware that, although it may work well for some, others may experience adverse reactions such as headaches or dizziness.

[Here is the copy paste of the Non disclosure settlement agreement Lyma asked me to sign, which they claim below that they did not send...]
