Revised Bit is junk (updated to a fivestar)
Finally got a chance to use it while building an Adirondack chair for the wife. Worked really well until about halfway through building the chair the bit snapped. They don’t seem to offer replacement bits that I could find. Amana needs to upgrade to a better quality bit and this would be a five star product all day. Update: Contacted Amana and they sent me two replacement bits. Top notch customer svc. 5 stars it is.

Works well but the drill bit breaks easily.
Excellent product when it works. I love the tapered drill bit. The problem is that the bit broke after using it only a few times. I can't find a replacement bit online. I am currently using it with a regular bit. Does anyone know how to contact the seller and where to buy the replacement bits?

Bad set screw?
Bought 2x for a large angelique deck install. The set screw stripped out on the first use, dropping the drill bit out. Spent almost an hour on the phone trying to have a replacement set screw sent. The other worked great--but we couldn't use it as we had to reconfigure a jig.

Great countersink!
I love the tapered drill bit and the ease of use for setting up the stop. Having used this extensively on a cabinet job, one thing that surprised me was that maintenance is required on these. I started getting swirl marks on my pieces from the stop not freely spinning anymore. I removed the lock ring and took it apart and it was completely clogged up with sawdust. After cleaning and lubing the bearing with silicone lube, it worked great again. I imagine this maintenance will have to be completed regularly which is fine in my book because it functions so well.

Overpriced junk
The bit burned on the first attempt to drill into a 2x4. Screw stripped in a few seconds.
