I got my EQ a couple years ago (I think?) and thought that some day I would get the DDAVE mod with the idea that it would increase my high some. I ended up putting it off until the bag filling elbow had a piece just drop off of it while I was cleaning it. Since I was pretty much bag only at the time, it was a major bummer. So I thought, what better time to get the DDAVE mod than now?
Was I in for a surprise! Not only does it work better in terms of high, I think I use less than a quarter of the herb! I really wish I got it earlier because I would still have a bunch of homegrown to tide me over until the next harvest. This only took a couple of months to change as well.
Don't do what I did, just get it along with the EQ. I really don't understand why arizer didn't make their glass like this. Hell, with how low it's going for now, you'd be paying about what I did just for EQ!
