The screws do an excellent job of what I bought them for - very high retention force to reduce the liklihood of squeaky subfloor joints. Retention is far beyond ringshanks. The plastic collation sleeves are a bit larger than I expected (makes sense, though; they do have threads, after all), making them more difficult to insert in my Bostich framing nailer, but they fed well after insertion. I had read urban legends that these needed much higher air pressure to drive than nails, but found that to be completely wrong; pressures are comparable with standard nails. In fact, heads are smaller than standard wood screws, making it easy to over-drive if you don't take the time to dial in the pressure. Overdriving in harder materials was found to result in heads snapping off occasionally, so proper setup is recommended. I went through a couple thousand of these for re-installing bone-dry 40-year-old 1-1/8 T&G subfloor with DF joists and found that they are very easy to remove if needed, and can be driven in with a standard screwgun as well (once de-collated). Overall, an outstanding product well-suited for specific framing applications. I did not evaluate any other applications.
