The Black & Decker Handy Chopper Plus is a small countertop chopper that holds about a large coffee mug's worth of material and lets you blend it at one speed.
There are a variety of times that I want to blend something quickly and don't have enough material to fill the large regular blender. If for example I'm trying to blend four kumquats to make a topping for my yogurt, the large blender can't deal with such a tiny amount. It would spray the cumquats along the sides of the blender wall and then stop doing anything. With this small handy chopper size I quickly and easily blend up the small volume I need and then toss the two halves of the plastic bowl into the dishwasher. It's easily clean for the next time I need it.
The unit is one-button operation. There's one speed, one mode. Press for on, lift for off. This means you don't have fine control over what you're doing. The only way to blend more is to keep holding down the button. You can't get it to go slower or more quickly.
Still for most situations that's fine. I can blend my kumquats at a touch. I can blend up tomatoes for a salsa. When we make Indian food it does wonderfully with onions, garlic, and ginger. The blades are sharp enough to handle most tasks I set at it.
We bought this in 2003 and I'm now writing up the review in 2011, so it's been a sturdy little device for 8 years. Just today we were blending up some kumquats and some of the liquid came out along the edge of the lid. So I think the lid seal is beginning to fail a bit. Still, after eight years, it's hard to complain too much about some minor issues starting to crop up.
Any down sides? Not really. Again, easy to use. Easy to clean. Does its job well. It was inexpensive and has never given us any sort of trouble.
I definitely recommend having a small chopper of some sort in your house. It makes it easy to use fresh veggies in your daily menu without much cleanup. Look for ways to make your own salsa, toppings, dips, and snacks, to keep the nutrients fresh and avoid chemicals!
