Your link is showing a picture of one of the Harbor Frieght 3pts. They are built kinda light, but are fine.
The early container load of these were built a little wrong. The place where your tractor lower arm is supposed to go in was crimped a little too narrow, & most tractor lower arm balls would not fit. Takes a bit of prying & bending to make them fit.
My understanding is the second containerload of these were built better, with the lower arm hole built to spec.
Just a head's up. HF has a sale through Xmas, $69. They also have a 15% off coupon for a lot of us, which gets it real close to the asking price there.
They work good, but - all your 3pt implements must be spaced the same, to 26 inches apart on the lower pins. Many are _not_ if you measure...... Then, the upper pin needs enough room for that top hook to slip below the pin & pick up. Again, many implements have some obstruction in the way, so that top hook doesn't work. You need to replace the bolts in the quick hitch with pins up there, and manually get the hook in the right place. Or, buy the adaptor that gets pinned in place manually. Or, modify, typically with a torch, your implement to make the hook work as it's supposed to.
Check your implements. Post hole diggers will _not_ work of course, nor will sissors-type pickup arms or bale stackers, etc.
Another alternative is Pat's Easy Change, which you can find at a sponcering web discussion board,
www.tractorbynet.com. They are to clamp-on bottom grab hooks, which are much more flexable as to different implement spacings, and sure do help in getting things hooked up.
The quick hitches like you picture work very well on bigger cat 2 & 3 tractors, where the 3pt implents are much more standardized. On cat 1 or the off-breed cat 1-small, a lot of manufaturerers kinda bypassed good design......
If your implements allow for it, that quick hitch will work well.
It & the Pat's Easy will both move your implement back a couple of inches. This will make very heavy loads that much heavier. And, if your pto is a little short, it will be too short now. Just things to think of. Most of the time no problem.
