I purchased this product because I saw a staff member using it at a beauty salon I frequent. I asked the staff about it and bought the same one. It's just a feeling, but my hair dries incredibly quickly, and it feels great. Sorry for my lack of vocabulary m(__)m I have confirmed that it works and is in good working order. The head part is melted and tends to come off easily. I was using tape to secure it. Since it's dangerous for my child to use it, as the head could come off and the tip of the dryer could touch their hair, we stopped using it. Actually, the head can be fixed by setting it parallel. I used tape as a support. Please be aware that there are marks from the tape. Adults should be able to use it without any problems by keeping a proper distance and securing it with tape or something similar. I bought a new hair dryer, so I no longer have a need for this one. The tape's hold loosens due to the heat of the dryer with daily use. I searched for the product number, but I couldn't find the exact same product (no mention of 4D Plus, etc.), so I'm avoiding stating the exact product name. The salon staff probably use it frequently. If you consider it a consumable item, I think it's a good deal, although it's only a small discount. Please understand that it is in the above condition and has been used before, and I appreciate your purchase and consideration m(__)m ※I will wrap it in bubble wrap, strongly protect the corners, and secure it before packing it in a cardboard box m(__)m
