One of my pet peeves is buying bunches of $3-$5 herbs (I love in Alaska) only to use them once and then have to toss them a few days later because they went bad. I bought this herb keeper with high expectations and I have not been disappointed! I've been able to keep bunches of parsley and cilantro for up to three weeks with absolutely no wilting. I make sure to change the water every few days or so to keep things fresh. I've also trimmed the stems once a week so they don't get water logged. My tactics seem to be working because they are still going strong. Yes, the larger herb keeper can take up lots of space, but I have a decent sized fridge and I'm able to store it in my refrigerator door with no problems. I may buy the smaller size for smaller bunches of herbs like dill and chives.
This herb keeper works very well. The water reservoir in this herb keeper helps to preserve and keep my herbs fresh for a longer period of time. Saves me money and allows me to get the best use of herbs in cooking! The only downside is that it is big/tall and takes a bit of space in my small well-packed refrigerator. It you have a large frig get this one - if your frig is compact or stuffed to the brim like mines - perhaps a smaller herb keeper would be better suited for you.
