Bought this at Smart & Final several months ago and first had occasion to use it this past week. Performance generally satisfactory, but the ratchet mechanism is so flimsy that use of a stiff mixture can bend or break teeth, rendering the device inoperable. My past experience with caulking guns (same mechanism) tells me that the designers didn't actually test it for use with the normal range of baking & pastry products. It's a shame, because the brand name is well regarded, and this product does not live up to expectations.
Redesign/strengthen the ratchet system and this could be a very serviceable tool.
