I really like this nectar collector, just not these new tips they have. Sucks up the concentrates too fast for my taste. I prefer the quartz over the other tips, but that's just me. Oh and getting used to a magnetic lid that is not a very strong magnet so the top popping on off alot may be an issue for you especially if you plan on keeping it in your pocket without some sort of case. I carry mine around with my concentrates in an eyeglasses case.
The pen is popular from successful online marketing.
The lowest setting on sessions mode is too hot for concentrate. Using the instant mode takes time to reach proper temp and exceeds it too quickly to complete a draw. Spend a few more on a different brand or just go with something that has a ceramic bowl. Either of those choices would have been better than a lookah. It is not a great device but will produce hot vapor that won't even perform great through water, either. Just go with that option brand you saw, IMO
