I received a dynavap for my birthday from a very good friend (purchased from your site).
At first I was skeptical as I had researched many different vaporizers, and just didn't know how to feel about the M cap. Frankly I probably wouldn't have purchased one myself based on my research and lack of information I was looking for.
However since it was a gift I tried it....
I was blown away this little M cap is INCREDIBLY delivering solid large hits with ease, very tasty flavour, and despite the interesting heating it's fairly stealthy (looks like a dog whistle). It stays cleaner longer than my other vape and has fast become my go to vape device, it's got a smaller chamber (bowl) but is very easy to refill so not a big issue. That being said I find it has better flavour and efficiency as you don't burn off the terps before it's all done like you do with larger chambers.
I love that if you just need a boost but not to end your day you can easily accomplish that by adjusting the chamber size (this is way less complicated than it looks) but can go from .10 to .05 of a gram. For a seasoned individual such as my self .10 is a good size as one fill I'm happy, can do my tasks and function, fill up a second time and I can function but and definitely feeling the affects, a third fill and now your at the same level as a large portable vape device.
SPEED this thing works faster than anything I have ever used (other than my personal creation of a vape). The heat up time is minimal and it delivers HUGE HITS, all and all to accomplish the same .30 gram session the dinavap beat the competition by about 5 minutes start to finish. So if your in a hurry this is fantastic.
Filling the device is just like filling a one hitter and can even be used in a Dugout box the same way, granted you must remove the cap to fill obviously.
Last but not least one of my favourite things is that with the STEEL SCREEN (there's a titanium option) can be done is you can put straight keef in it by itself straight from the bottom of your grinder no sandwich or bottom layer of flower needed. I found no information on this so I tried it multiple times, I found as long as you take a average to slightly slower hit you don't get much if any pull through (if you do its very very small and stays in the inner tube and does not end up in your mouth). I personally love this as if you're really in need of a super fast powerful boost it will definitely accomplish that. I would recommend checking the chamber after 2 or 3 heat click cycles as occasionally (with just kief) it sometimes needs to be stirred (not with flower) as sometimes the kief in the middle doesn't get quite as hot.
I will say there's a tiny learning curve for this device but it's not hard to learn and then works fantastic. For example depending on where on the cap you heat and at what intensity the flame is in proximity to the cap can deliver different amounts of vapour and flavour and how many heat cycles per fill (usually 2 - 3) is sufficient. You can easily check to see if it's done by removing the cap (obviously once it's cooled enough to handle) and look at the contents if there's any green colour left heat again if it's light brown it can be cashed or hit once more, if it's dark brown it's done, if it's almost black and tastes kinda like burnt popcorn it's definitely done.
Cleaning is super easy, at first I watched a video with instructions and was concerned it was complicated, but it's really not and has everything you need to disassemble or reassemble as part of it so no other tools needed, and It stays cleaner longer than other devices I have used plus clean up is faster. As for replacement parts so far I have had and used my dynavap for about 8 months with heavy use and never needed to replace anything yet. This is especially phenomenal because my other battery unit has needed gaskets once so far in 6 months of use.
I hope this helps you make an informed decision in your future purchase.
