I purchased this 16ga trimmer and a 12ga trimmer from Ebay on February 10.
They arrived Saturday March 11 with tracking information provided by seller. It was a very professional transaction.
I'm pleased to say these are very well made, SOLID and durable.
You can chuck them into a drill but I just trimmed some hulls manually. One spin and done.
Price was very reasonable at $19.99 each plus $12 shipping for one or two pieces.
If you are looking for a good hull trimmer this is an excellent option.
