I was very nervous about purchasing this dryer since there were no reviews on it and so far I’m pleased. Although it came in a very large box the dryer itself was very light weight (30lbs) and easy to assemble. The panel where the control buttons are, are very simple and tactile, I didn’t even need to use the instructions. I’m not entirely sure if this dryer uses infrared technology for processing, but it does get pretty hot but not hot to the touch and it’s super super super quiet you can still have a conversation, watch tv, or talk on the phone without the loud typical bonnet hair dryer sounds. My plans are to use this dryer for deep conditioning, hot oil treatments, and roller sets. I will come back with updates as needed!!!I am happy with the purchase because the price affordable and the product works well and does it’s job. At the beginning I was skeptical when I saw this item without review, and no free shipping prime, but I see the price is much cheaper than others even with the shipping fee, I just want to give me a try, now I’m glad That I made this purchase, I’m happy and satisfied with this product and the seller because they support all the way to make sure you are happy with all your questions and help. I highly recommend this product and this seller to anyone who need it. Thank youEl secador llegó roto no calienta nada y el me cuesta más de la mitad del costo del producto por debolverlo no recojo el comprador para nada
