I've been using the Gr8tr grinder for a little while and must say it does a gr8 job and has an exceptional build quality. I use the fine grind plate mostly because I vape a majority of the time. It makes my herb fine and fluffy and just right. I didn't get the version with the screen because I use a kief box, but I wish I did... just more options.
... it would be this one. I've admittedly only had this a few days, but damn if I'm not in love. Fit and finish is superb, and every detail, inside and out, just seems to have been considered carefully and then done without compromise. I've turned it over and over, looked inside and out, and I can't even find the smallest blemish or burr. I've been using the fine grind plate that it comes with, and that worked perfectly in my Davinci IQ. Beautifully uniform output. Highly recommended.
I have to admit I was a bit disappointed in my purchase initially but that was my fault - I read it incorrectly and thought I was getting the screen, just not the storage area. Now, I have to admit the whole reason I bought the grinder was for the replaceable screens - get tired of them clogging up and thought it was a great idea. I haven't had a grinder without a screen since the 1990's and really thought I needed it. Don't know why, it's fine without one. Never could build up enough to make kief- I'd always use it. Now, I'm really not sure I ever needed a screen. Think about it, you may not either. This is the smoothest spinning grinder I've ever had and I really like the little grip lines around it. The rounded edges are nice to hold as well. All in all, it was one of my best buys ever and here I thought I had made a horrible error. Never too old to learn.
