SPECIFICATIONS: The two dice grid-blade options are 6mm x 6mm (1/4" x 1/4") and 9mm x 9mm (3/8" x 3/8") and the slicer cuts 6mm (1/4") wide halved slices. The total cutting area of the squircle-shaped blade insert is ~73mm x 73mm (2 7/8" x 2 7/8"). SALSA AWESOMENESS: I make a lot of fresh salsa (pico style), and cook with a lot of fresh produce, but find the chop-chop-chopping to be tedious. With a little prep, such as trimming, peeling and quartering/halving, the Norpro makes quick work of pico ingredients, uniformly dicing raw (firm) tomatoes, onions, and peppers. IT CUTS: The unit also works well with raw potatoes (note, this isn't a french fry maker - smaller pieces are required), carrots, and is great with celery (whereas, my food processors fights with the strings and tends to create a mush). Chopping apple quarters down into slices and sticks is easy with the Norpro. IT WON'T CUT: The Norpro fails on skinless tomatoes (cooked or raw) and dried items (e.g. sun-dried tomatoes, dried peppers), and soft produce like heirloom tomatoes. They don't cut well, and make more of a mess than is worthwhile. CLEANING: The handle has a clever detach mechanism (as do the pusher piece and blades), so cleaning is straightforward. Debris can be trapped in the intersection of the blades, which is the hardest part to clean. UPDATE: after using this tool for longer, I've found the blade intersections to be challenging to clean. Some materials are easier to remove dry - others when wet; its a bit of trial-and-error. USAGE TIPS: If you're slicing apples, always place fruit skin up in the slicer; for something like a mushroom, I've found placing them in cap-up to be the least messy/wasteful (debris can accumulate in the pusher). In general, you want the most resilient part of what you're chopping facing the pusher and the softer part facing the blades. Also, if the hinge mechanism sticks, food-grade mineral oil can be used as a lubricant (don't use vegetable oil, as I initially did). 6-MONTH UPDATE: The stainless blades started to rust after regular use. It's difficult to extract all the water from the seams after washing, but Norpro replaced them for free. 2-YEAR UPDATE: After a few years of regular use, the most-used blades became dull, necessitating substantial force to slice and dice. Still, the plastic components show no wear (aside from UV yellowing). I made a request to NORPRO to sell the blade inserts separately, since they'll dull long before the other parts fails. 3-YEAR UPDATE: The second set of blades have dulled, but the rest of the Chopper is holding up great; I can still use it, though I need to push harder now. REPLACEMENT BLADES: Norpro Customer Service sells replacement blade inserts - $8 for dice, $7 for slice (Shipping and handling included in the US). They also sell replacement pushers. The durability of tool, combined with the replaceable wear parts make this an easy 5/5 stars buy for me.
