Decent as inexpensive boxes go. Keep it 1/3 full or more, store it on it's side or upside down so it won't leak on you. Make sure reservoir cap is screwed in tight before putting the thing in a purse or pocket - it will leak if not.
200 is WAY too much for it, on sale at several vape shops around here for 49.95 to 51.95, some with a free 30 mils of juice with them, some with free battery, some free boils for it. One shop, all of the above and a buy one get one free sale going on that go me 2 NEBOXes, 10 extra coils and 30 mils of premium juice for 59.00 (taxes)
Don't pay over 60 for one, not worth more than that and, you can get them for that.
