Solid and they work great. Have to re tighten the legs here and there. My Dancers like them. I also have the lighter bars from Vita Vibe and they also work great.

Very solid!  I'd give 5 stars but why put round holes in something that's designed to be recessed?  If the holes were square . you could use carriage  bolts instead of hex heads that stick up. Other than that they're great.

Very solid and well made. They have indentations that allow them to stack without having to worry about them sliding out of alignment. I had to return mine, as the patio umbrella I got them for had a larger diameter support shaft than these weights could accommodate.

I would gladly buy another set if they had one that would fit the patio umbrella I have set up.

Chairs are great and solid however we had to drill new holes in one arm on each chair because they did not match up to the pre drilled holes so get your drill ready. Still very much worth the price and the good quality. Love them!

I used these to secure 3 posts along a stair opening in a hardwood floor. They made a very secure and solid connection resulting in a solid post. The only drawback was that my 3/4" wrench to tighten the nut had a rather thick body. This caused some difficulty tightening the nut. Use a narrow body wrench and you should have little problem.

They work great and are really sturdy. The slide out a bit too easily, so I'll have to tighten them, but I'm pleased overall.

Nice mounts.  Be careful not to over tighten them as they will crack the cast aluminum mount.  I had to buy a second pair due to my overzealous cranking. LOL. Rock solid.

These work great, my basement floor is not completely level in some spots so the adjustable legs are very nice to have.

They work great.  They are a little tough to seal and then subsequently un-seal, but they are solid.  One did somehow get cracked in the corner so it won't hold liquid well.  Thankfully we have plenty of Dry goods in the pantry and it works just fine for that.

Very sturdy when (finally) put together and working just as I needed. As other reviewers stated, though, the legs are incredibly hard to attach because the wingnuts aren't sized properly for the screws included.

These are holding my Samsung 28" monitors perfectly.  They are strong and allow the movement I desire.

One note is that I was hoping to have my monitors lifted off of my desk quite a bit, but because the VESA mount on the monitors is not centered, and is towards the top of the monitor, my monitors ended up being at the same height as before.  By flipping them upside down, I have gained the height, but have to deal with issues such as viewing the monitor at angles for which viewing wasn't intended.  Ultimately, the setup works, but I wanted to mention this in case someone had the same plan.

This comes with the connector/clamp as shown in the picture, but also a second option for mounting.  I'm not clear of how that works though.

Very solid, works great when installed correctly. Like any hardware, it has to be installed precisely to avoid binding or excess play.

I installed them upside-down on windows, they stay latched even when the wind is blowing and rattling the windows.

If they bind a little, white lithium grease would probably help but I wouldn't grease them if installed upside-down...might make the detent too slippery to stay up if vibration occurred (ie wind).

Solid and sturdy. All threads are a tad bit long, might need to cut them down and cap them off with acorn nuts. Mounted mine to passenger side firewall.

Super solid. Minimum height is still pretty high, but perfect for me. Slants forward a bit too much, in my opinion. The clamps are excellent if you need them, so be sure you buy the right product.

Work very well. Just make sure your platform pedals have slots big enough for the thick straps to pass through.

If they fit, then the footstraps are beefy and hold very well.

I was really worried these would be shotty and rickety but they are quite smooth and solid. My only complaint is their length which makes some basic exercises a little awkward. Very well made though.

This is a very solid product and all metal. There is one problem that is coming up in many reviews about not being able to tighten the swivel ball to hold a camera very well. I bought three of these and the problem is this simple: the threads on the thumbscrew are half painted therefore they don't screw in far enough on many of these units to tighten the ball. One smart fellow swapped the set screw which is opposite the thumbscrew and it worked. But he missed the reason why. The set screw just screwed further into the hole and engaged the ball. If you either get new thumbscrews or clean them by using I think an 4 mm nut (but check for yourself at a home improvement store) - just turn the nut on/off with a nut-driver or pliers a few times (you can't sand or file them or you'll mess them up). Once the threads are cleaned they work great and would hold a 10 pound camera I think, as this is a very solid all metal product. Someone goofed in China and painted half the thumbscrew threads. Note the setscrew needs to stay where it is because it resides in a channel that keeps the top from falling off and also can be used if you turn it in all the way to prevent the top from rotating. This is a very nice product.
