I bought this to add on to my regimen of daily minoxidil and finasteride. It is much cheaper than the options I was looking at Costco, which are hundreds more. So, I figured why not give it a shot haha.The packaging is decent, but most important to me was if the product was decent in quality and function. One concern was if the cap would do anything given how much cheaper it is than the brand name options.The cap definitely gets warm even when not on the highest setting, indicating to me that it is likely working as intended. My scalp definitely feels a little bit more rejuvenated and warm after use. Of course, it will takes many months to a year of daily use to see if anything actually changes. I don't know if it will make a difference to my hair, but as long as the product works as intended, then I think I have received my money's worth.The manual is clear, and the cap can work on a battery bank or wall outlet power which is good for travel. I had no problems figuring out how to use it.The cap fits me well and I have a large-ish head. It is adjustable with a strap in the back for, though. It only comes in black which I think is the best color as you will sweat while using this cap. This way sweat stains will be better hidden. Also, the item comes with sweat pads (?) but they're not very good. I use it without them.Overall, I am satisfied with my purchase and you should try it too if you're on the fence. For what this is, the price is a bargain compared to other offerings on the market.
