A $200+ sight pusher just isn't in my budget quite yet. But the really cheap ones seem to have some rather coarse threading on the pusher, leading me to believe that they might be difficult to use precisely. I saw a sight pusher on Amazon that looks a lot like the expensive sight pushers for about $50. This pusher may be used for front or rear sights. I decided to take a chance knowing full well that it might only be a sight pusher shaped object.
The first problem out of the box is that any part that was threaded seemed gritty and was not turning smoothly. I started to disassemble it. The handle that turns the threaded rod that moves the pusher was loose. The set screw was not tight. Typical Chinese product. After disassembly I cleaned all threaded parts. As you may have guessed, there was a considerably amount of crud in the threads . Again, typical of products from the People's Republic of China. I lubed the threaded parts with Mil-Comm TW25B synthetic grease with teflon. I could have used Redline CV2 synthetic grease, which is my go to grease that works very well, but it is stinky, so I used the Mil-Comm grease instead.
I noticed that the two large threaded studs were dinged up and that the chrome plating was coming off. I could scrape off the chrome plating with my fingernails! Again, I wasn't surprised. The two huge knurled adjustment nuts on the top of the sight pusher were NOT tapped perpendicular to the shoulder of the nuts. Again, not surprised.
After cleaning and relubing all adjusters rotate smoothly. In fact I can now spin the pusher adjuster.
But now to the most important part, the actual pushers themselves. It has two. One pusher has parallel sides and the other pusher has angled sides. In order to switch between the two pushers you turn the pusher adjuster and move the pusher all the way to the right. Then you rotate the pusher 90° on the threaded shaft until the top tab on the pusher lines up with the groove in the pusher upper body and then reverse the rotation of the the adjuster rod and move the pusher to the left
Now the major problem. The pusher is too wide to fit into the dovetail groove for the sights!!! Apparently they expect you to place the pusher at the side of the sight instead of at the side of the dovetail on the bottom the sight. Some people claim that pushing at the side of the sight can damage the sight and I'm inclined to believe it.. It should be safer to push the dovetail area at the bottom of the sight.
I'm not going to return the sight pusher. Instead I'm going to grind down the width of the pusher so that it will fit into the dovetail groove and push against the dovetail area near the bottom of the sight. I fully expected there to be problems with a sight pusher that is this cheap. I wasn't disappointed.
If I was an armorer as a profession, there is NO way that I would buy this. But for my own use on a couple of pistols I don't minding spending some time to make this pusher work correctly. I would NOT recommend this sight pusher unless you are handy with tools and can do a good job at grinding the pusher to size. Even then it might not be worth your time.
I'll update this after I've modified this sight pusher and I get my new gunsights and try out this pusher.

Note that in the following video the actual sight pusher presses on the side of the sight and does NOT push on the dovetail edge.
