I purchased the Hydrologic nx just before 420,I personally waited a month to write the review to insure complete accuracy for my fellow vape coinsurers. QUALITY=🌟🌟🌟🌟🌟🌟,If there was 6 stars it would be appropriate. Everything is magnetic in one way or another. Utilizing technology at every aspect. RELIABILITY=🌟🌟🌟🌟4 Stars mine came with a battery that needed conditioning, the first week the battery was failing every session, Cust service was slow most likely because of 420 flood of sales. SERVICE= 5 star -shipped a new battery next day air PERFORMANCE =5 🌟🌟🌟🌟🌟 Stars with the 6 different light spectrum it's hard not to find a flavor you absolutely Love. EASE Of Use = 5 🌟🌟🌟🌟🌟Stars, a bit intimidating at first but the manual is very clear on every procedure. This is simplicity colliding with technology. Auto off Turn dial color temps on the fly. Easy load desired results in minutes 5 STARS 🌟🌟🌟🌟🌟 MOBILITY =4.5 🌟🌟🌟🌟Stars It is the perfect size for the quality that it is, I got the case so it's protected. I just put in my laptop case If you want the ultimate in vaporizer The NX awaits you for complete satisfaction. Over all Rating🌟🌟🌟🌟🌟. Its as good as vaporizing gets with all the bells and whistles even a light show during every session. Thank you Cloudious
