Bought one more than a few years ago. Paid for itself within a year by buying whole olives on sale instead of the pitted ones.
Bought one to pit cherries for pickling and preserves.
I have it, and use it mostly for cherries. We DID use it on kalamata olives when my youngest was to young to deal with pits.
Dang it you guys. OK, I assume you have olive stuffers too? I'm stuffing Queens with my homemade blue cheese this afternoon.
Right now I'm transferring my tomato plants from pots to garden on south side of house. They got WAY too big for the self-watering planters/cages and keep tipping over. Ugh.
