Perfect! And the tightening knobs are easy on the hands.

Nice and tall with lots of clamps, secures to the base very tightly IF you use some kind of gripping washer under the bolt. I used a piece of rubber to apply friction to stop the bolt coming loose

The stand is okay and does its purpose. However in an environment where it vibrates its not going to work out as well. I'm glad I'm not using them in that environment. The kit comes with more than enough arms to hold all sorts of glass. So far it holds everything I need! If you can get some blue lock tight on the nut that holds the bar to the foot, do it. Maybe even a red... Anyways, I'm happy with them!

Once again, Vevor had shipped me a quality product in record time (

item works well , and is sturdy. It arrived fast, and packaged well. You must know how to properly use the item, as improper use could cause breakage of glass ware and chemical spills

This set of ring stands is a good buy for the set of 2. I use it for school science. I like that it comes with so many different clamps. It is not as heavy metal as those you'd buy from a scientific supply company but it works for me and is so much better priced. I had purchased several sets for a previous school, moved to a different school, and purchased 3 more sets.

These stands are nice, but they can flip if you use one of the pincers to hold a slightly heavy item too far away from the axis. They’re perfect for microscale operation, though (although I would've appreciated smaller items.

Works well, only a bit unstable under heavy objects. For the price, it’s well good enough and useful.

Quality: poor. The screws and thread points are very cheap and easily strip when tightened sufficiently. After performing a 30-minute test distillation of water, most of the parts formed rust spots. Bases are so light that cannot support glassware; had to purchase large lead weights to add to the stand. Feet on stand are not heat/water resistant and needed to be replaced with silicone feet. Price: poor, because after fixing everything that was wrong with these, I could have bought better quality stands in the first place. Hold capacity: poor; the base cannot hold even the most fundamental apparatus without additional weight added to the base. Additionally, the screw hardware is scarily cheap and doesn't hold well. Conclusion: buy these for parts, or for non-toxic, low temperature work only. I wouldn't let my kiddo in AP chemistry use them.

Quite light-weight, not very strong, and wobbly. Not anything like an alternative to a professional lab stand.
