Great vapor density and flavor. Super easy to clean. Super easy to use.
Just hit the switch, wait a min, and that's it!
Once you turn it on, the device maintains the perfect temp until it is turned off. So I can walk the dog with it warming up in my pocket just letting it idle while keeping the correct temp (It does not get hot to the touch) and then just pull it out for a quick vape while on the go. (Just remember to turn it off again eventually, as there is no auto-off that i know of.)
I let it run for a while to test it to see if the device would eventually burn the cap contents, but I can say it did not at all. It also seems to use all the contents right down to the end without any thing wasted.
I haven't been using the optimizer, but I don't think it needs it. All the contents are heated evenly, and only have to stir it all up maybe once per cap load.
The only cons:
-There is a faint butane smell while it initially warms up, but that odor does not effect the vape taste or quality so I don't really find it to be an issue.
-They are a bit pricey, but I got mine on sale for $188. So not an issue (at least for me) ;)
-When warming up, there is a hissing sound(or "wisper" I guess) but its not as loud as I was expecting, or as loud as some people say.
-You can't adjust the heat level, but this thing always just goes to the perfect temp. Never too hot or too cold. I personally like that I don't have to fiddle with setting the temp and it makes it easier for others to try...So again, I don't find this an issue either.
If you see one cheap, jump on it!
Some people been giving this low reviews, but this thing performs above expectations for me!
I found it works best if you:
-fill the cap with 3/4 the way up.
-Use only the 5x filtered butane (like Vector) and fill with butane can and the Wispr turned upside down. Also give it 5-10 mins after refilling before using.
-Let is initially warm up a bit for 2-3 minutes (I know it say 30 sec, but you get a much better results if you wait just a little.)
-When turning the gas on, let it fill to a 1-2 seconds before slowly pushing down the ignition. I can get it to light on the first try about every 9 out of 10 times.
