I plan on keeping this grinder until it wears out.
Positive Product Points
The grind quality is very high. This grinder is a looker. The price on this particular model is very attractive. Infinite grind control.
Negative Product Points
A large amount of coffee is left in the chute and under the burrs. This is not the quietest grinder, but not as bad as I had feared. The fork height is not adjustable, and may be too close to the chute for some portafilters. In the conical burr model, the burrs are mounted on plastic. As a new product, its durability is unknown. Its tall enough that it may not fit under cabinets in some kitchens.
I decided to get a new grinder because my previous grinder, a Bodum Antigua, could not grind fine enough for my espresso machine. In looking for a new grinder my main criteria were price and grind control. After reading reviews and looking at prices, the Innova conical doserless grinder jumped to the top of my list. When I received it through the mail, I disassembled it to ensure there were no obvious problems. I noted that the burrs were somewhat smaller than I had expected. The small grinder area could result in heat build up, especially considering the high rpm of this model. I also noted that there is a large area below the burrs that collects stale grounds. I discovered that the exit chute is very difficult to remove, as it is held in place by both a screw and some adhesive. The manual suggests removing the exit chute to clean it when necessary, however that is clearly not practical due to the adhesive. After reassembing it, I fired it up. I fed it some stale coffee I had laying around. This grinder is pretty noisy, but I was expecting this. Really, the noise was not as bad as I feared it might be. What I really wanted to know was if it could grind fine enough for my espresso machine. It definitely can. If you need to turn coffee beans into dust, this grinder can do it. The biggest problem I ran into was that the chute would fill with grinds. It is fairly easy to remove most of them with a spoon handle or the like.
I ordered this grinder over the web during a sale. Unfortunately they oversold the product, and I had to wait a while to receive it. Otherwise, my buying experience was completely satisfactory.
