So I started using this gun and it worked pretty well for putting down underlayment for the basement finishing project I've been working on (basically screwing sheets of plywood together).

First, the overall performance of this tool is really good. It is better with a 4500 RPM screw gun (with adapters the collated attachment itself is compatible with most major brands of drywall guns) but the collated adapter certainly speeds up this kind of job and the longer reach attachment really saves your back when putting down subflooring or underlayment. For my specific job (screwing sheets of 1/2" plywood together) the correct screws make a world of difference. For this kind of application get underlayment screws, anything else will strip the plywood and require repeated attempts to re-drive the screw with another drill/driver. However my issue isn't with the tool so much as Senco.

After a little break in period the bit became much easier to remove from the screw gun. Which would have been fine but it was getting caught in the plastic collating strip that holds the screws and pulled out by the mechanism's return spring. So I called Senco and the guy said I was missing the "bit retainer" which had likely fallen out when I was putting adapters on or taking it apart. So I ordered some directly from Juldan (who ship super fast and have an excellent selection of parts and tools). Turns out the service guy from Senco told me to get the wrong part as he'd instructed me to get the bit retainer for the Senco DS300-S2 Duraspin 2500 RPM Collated Screwdriver with Extension Kit screwgun (drives longer screws). So I called up Senco again and told them that the bit retainer wouldn't actually fit since there wasn't any place to put it. I asked them to send me the right part and they did. It arrived in a couple days and I was finally up and running again.

I found that the bit retainer assembly for the DS200 includes the bit retainer for the DS300 which is simply a small part that clips in to the larger piece of the DS200 bit retainer assembly. I had to take apart the collated attachment to put the part in, in other words, it shipped missing a fairly critical component and was no fault of mine that it was missing.

So I'm glad they finally made good but I'm not really impressed with their customer service. Telling me I probably wasn't putting the gun together or taking it apart correctly, and not shipping a $2 part for a new tool that is suddenly non-functional is not the way to win favor with a customer.Get more detail about Senco 790004N / DS200-S2 Duraspin 2,500 RPM 1-Inch to 2-Inch Screwgun.
