I don't know if I should give this thing 1 or 5 stars!!!

I have to start off by saying this thing is amazing. After the first use I was looking at it like ***, this didnt do anything just to realize it had actually filled my cone so fast and effortlessly I just assumed it did nothing. I immediately "rolled" another and actually watched it work this time and I have to say it's crazy cool. It actually works, I tried one of the included cones and then 2 of my Amazon jware cones and both worked fine.

With all that said it has two problems. The small problem is it doesnt pack the cones all that well. The instructions recommend tapping it on the table as you fill and shaking after, and frankly if you do both of those things the cones come out just fine, but the push and go experience of the grind instantly spoiled me.

The second issue is it makes rolling way too easy. There is no reason to smoke any other way now. This thing is going to be a huge burden on my wallet because I'm about to go through my **** so much faster.

In all seriousness this thing is great. If you like joints and are even remotely lazy this thing is a must own. Came boxed well with good instructions, banana bros has done well here.
