These are fantastic. I use them for herbs, sure, but I also have been using them to cut up things like pepperoni, apricots, green onions, celery, etc. Even tried chicken once. They do a pretty good job, although the blades can move/flex a little (side to side) with larger objects, making some pieces larger than others, and sticky things (like dried apricots) can get stuck in the blades. But a gentle tap usually dislodges them (or the use of the opposite end of the blade cover). However, not really a product flaw, as I'm sure they're not really intended to be used to cut apricots or shred chicken!Dishwasher safe, too, so far (which is great for me, being lazy).Bottom line-- these save me a LOT of trouble and washing of knives, cutting boards, etc. Love them!
