"A money saver"
From reading other reviews, opinion is certainly divided about this product. I'm a supporter, and have used one successfully for ages. I feel so virtuous when I use the herbs and guiltily remember all those half packs I wasted. I've even kept basil in mine. Thanks to others for the tips on spring onions and asparagus - I, too, found this works. I've been inspired to try celery( yes - it keeps crisp and fresh if you trim and wash it first) and wonder if a trimmed little gem lettuce would keep in there. I'll let you know. Actually - I don't unscrew mine and fill and refresh it from the top, when empty. Am I missing a trick?
