Review (1/5): Do not buy! Came to me broken.
Device did in fact appeared sealed but still looked like it had been pre-used. Device tip was already raised and bent at 90% rendering it useless. Box in bad condition and label stickers partially broken and or messed up on Device. If it wasn't so cheap or I wasn't in Hawaii I would deal with getting my money back but unfortunately that is a huge hassle out here. Please just save money for a better option or go to a professional. What a waste!!!!
