They are OK. I didn’t seem to get as high. And they seem to go really quick it’s just me using it and I know how fast they go cause it’s just me because I’ve been using them for a couple years now just that brand and the same had a little battery pack thing and these ones just go by within that like a day and a half two days and that makes no sense because I’m not like constantly smoking it but they were very inexpensive so I guess you know you get what you pay for. Otherwise the company was wonderful to work with and the driver was great. The people on the phone were great. They were very easy company to work with.
