Works fine. To start you have to long press the button.

Great product. My scalp hasn't been this clean in a long time. Highly recommend.

Very nice device. Pleasant to use. I think it will be useful and effective.

Came really fast and was extremely well packaged, not a single dent in the products box. Can't test it now since it's a christmas gift but so far i'm happy

Super

Very important: Press the adjustment button for a few seconds. I thought the product wasn't working after charging it, but you just need to press it longer. It's great, massages the scalp well, and adding serum or oil works well too. Helps with scalp care and hair growth.

super gently massages the head I like it a lot

I still don't understand how it turns off, but it works well and the massage on the scalp feels pleasant. I need to see how it works with oil, but I really liked it. I recommend it for relaxation and to enhance treatments for hair loss.

Fantastic massager. I use it every day and it's a moment of relaxation for me. I thought I would buy something and wouldn't want to use it, but it's so pleasant. I recommend it.

I recommend this super device, it's a mega pleasure.

Revelation, wonderful device. Thank you sincerely.

I recommend it but for people with sensitive skin. For me, this device harms rather than helps.

seems not bad but slight adjustment of massage

Scalp Spa™ Electric LED Massager Comb

It massages the scalp very nicely. I haven't tested it with a hair scrub yet, but I think it will be fine 👌.
