Works pretty well for small diameter bits. Binds slightly during use when pressure is applied, but if used carefully, does the job I intended it for.

I have an old hand drill from my grandfather. This is a good backup. My grandfather's is still working after almost 100 years. I'm pretty sure this one won't last as long. But it does seem sturdy enough for woodworking or soft metal drilling.
The chuck seems solid and well designed. It's better than I expected for the price.

1. Chuck-installation instructions are not included with the drill or the chuck. Install the chuck according to the diagrammed instructions on the Amazon product page. When mounting the chuck to the handle, hand tighten it thoroughly (if you can, all the way down to the bottom of the metal thread on the handle). Then, open the jaws and install the screw.

2. On my drill, the front gear (nearest the chuck) hung up slightly as it meshed with the orange handle gear. It worked, but not smoothly. It wouldn't have affected use of the tool, but I fixed it by pressing the gears together and forcefully moving the gears back and forth over that spot several times. That resulted in smooth operation. Apparently, the orange coating on the handle gear was slightly too thick at one point and it required some use to wear it down.

3. I needed to drill 3/8" holes in drywall for 6S Molly fasteners (the 3/8" drill size is specified by the manufacturer). I have a power drill which would accept a 3/8" bit, but I prefer a hand drill for drywall -- it produces a cleaner hole, more suitable for Molly installation. This hand drill worked perfectly. I am pleased with it's quality and value.

While drilling it can bind but it's not the fault of the tool. Use sheet metal drillbits, not wood and it will bind less. The binding is primarily from the drill bit biting into the wood. The less the bit bites the smoother the operation of the drilling process. Putting some petroleum jelly into the 2 gears on the rod portion of the tool will help as those gears can slightly bind against the housing under pressure. For a manual drilling tool, I like it.

Better than expected hand drill. The keyed chuck makes it even better. You can tighten up a bit enough to not have any slippage while drilling a hole. The only problem I had was the red hand crank/gear was not tight as it should be to prevent some wobble. This was easily fixed. I don't know why some people had problems putting the chuck on as I thought it was very straight forward and easy.
