The funnel was really hard to open underneath the grinder.It works great but you'll have to pack down your cone a little bit at a time which requires you to remove the cone then reload it back in while getting flower ever were. Very messy only down sideWhen I ordered this, I thought that the tube inside would function like my loader - I thought the cone would slide over it. But you actually put the cone inside it. I used a packing stick to open it up the whole way. Then I used the stick again to pack the ground herb down, because a lot of it stayed at the top of the funnel. Overall, I do think I made less mess this way than I normally do with my separate grinder and loader. I think making it so that the cone slips over the tube would be a design improvement, but that's the only change I would make.Everything was good but not the grinder itself. I use a different grinder to packIt's not durable, cleaning and packing tool missingWorked ok, but kinda messy and not as easy as it appeared it would be to use.Simplicity is best is that’s what you get hereThis is perfect for someone who sucks at Rollin the traditional joint and the cones are so much easier and burn better. They don't run down the side they do get stuffed funny so stopping and pushing the green down in between grinding is a must or you end up with a half empty middle full joint. But if I could I would recommend this to any joint smoker I love joints it's my preferred way to smoke and they made it super easy and affordable. Thanks keep the great ideas coming and make my smoking habit easy-goingThis thing is one of my favorite pieces of "paraphernalia" . Cones fill quick and clean with the grinder in the lid.
