I purchased the NX bundle at x mas for myself because I enjoyed the original so much and was excited to see the one that did concentrates. Well all was good except the cloudious 9 was hard to turn on sometimes taking 5 or 6 times to get it to come on. I contacted cust service because a previous issue with my first purchase was handled quickly and with no hassles. That wasn't the case with the current issue. Since you are no longer handling cust service in house they wanted videos and detailed descriptions and it really disappointing if it wasn't for the fact that the C9 is my go to traveling vape so I just bought another. Hopefully I'll never need the 2yr "no hassle " warranty
