I bought this for a friend to treat his sinusitis/rhinitis as it's very portable, and looks good. Both lasers are bright, and the LEDs really light up his nose :-). Grace from Laspot was very helpful - this is a new product so the instructions were in Chinese only. She emailed me the English pdf file, and also the video link on how to use it. Actually, it's pretty intuitive. Shipment was by DHL. Very fast. Only thing now tis o see if it really has beneficial effects....
