Purchased this product last week at the full price(just my luck) However, excellent product well made and does the job for anyone with a little hint of knowledge. Most reviewers seem to have a problem with using this item to inject jam into doughnuts! Why! Simply warm your jam(preferably seedless for obvious reasons) add a little lemon juice to set the jam once injected into the doughnuts. Unscrew the handle device, fill with jam from the top end, fill with jam/lemon juice mixture and away you go. What could be easier than that? Thanks for reading.
