4"x4" Stainless Steel Lab Jack Mini Scissor Lift 6.6lbs Load Capacity | Laboratory Double Scissor Lift Table Expandable Lift Height Range 43mm-150mm for Laboratory Tool

First things first: Don't buy this if you are planning on trying to lift, pry, or spread apart anything lighter than a few ounces. It will work fine for what I bought it for, which is positioning small objects in front of my camera while doing macro photography. I bought this because it was about the least expensive one I could find, and I don't plan on using it daily. The top and bottom plate are very thin stainless steel. The corners are rounded and the edges are smooth enough to run my fingers along them without getting cut. The knob is cast plastic, and a little small for my large hands, but adequate. Everything else is Zinc coated steel. The adjusting threads seem to be standard course threading, so micro-fine movements will be difficult. The bearing ends of the axles are just ground-off threads on the ends riding in slots cut in the spot-welded angles. If you use this a lot, under moderate to heavy loads, you are sure to wear a groove in the axle ends. There is no lubrication on anything, which is fine with me, that way it won't stain anything right out of the box. There are four rubber stick-on pads on the bottom. With all that said, I give it five stars since I paid less than twenty dollars delivered to my door! I won't use it with heavy loads and I won't be using it every day. I'll add some clean lubricant (light sewing machine grease?) to the wear points, and I will have it in the middle of it's travel most of the time. Other, higher quality (and more EXPENSIVE) units would be a waste of my money.

This little jack stand lift works great. I love it. Instead of constantly shifting my camera around to try and capture a macro subject in the frame, I can move the subject to the camera using this lift. It's much easier and less time-consuming. It seems to be well built, and it's held up well. Overall, I think it's a good product which I found quite useful.

I needed this to hold up a HVAC housing under a dash. It worked pretty well. Raising it was hard out of the box. I lubricated the threads and all pivot points, made some adjustments to the friction nuts and got it working much better. Id buy one again because, this type of lift jack is hard to find, so it was worth the price, even after having to mess with it. I'll be adding a non-slip pad on the top surface.

I use this for adjusting my laser level when I am on a job site. We used to stack up pieces of wood to get the correct height. This is so easy to dial in and the size fits our levels perfectly. The compact size even fits in the laser level carrying case

Excellent adjustable stainless steel stand. Very well made and very stable. Easy to adjust height. Extremely happy with this. I those this one due to very high reviews by prior customers and agree with the praise they gave. Strong recommendation!

I've tried both a 6x6 and 4x4 for installing garbage disposals under sinks and they both work although the 6x6 is probably the best choice.

I have this lab jack going up and down to get the herb holder of this vaporizer into and out of battery. Every time we want to load/unload the contents of the herb changer this lab jack going up and down almost its entire travel. It has so far probably done this cycle 200 or 300 times, and so far everything is still smoothly functioning. Will update in a few months. And if anyone is curious, that is an Aromed Vaporizer... it is a 1 of a kind herb vaporizing system. Noone else has ever made anything like it. UPDATE I have gmhad this setup for several months, and would like to write an update to tue review. The Lan jack has probably run its travel 1000 times at this point, and I have started to feel the wear and tear. This lab jack was not designed to go up and down 100 thousand of times. It has developed slack in the mechanism. Originally the design was to run the travel every time it needed loading and unloading, but it is well on its way to wearing out. Since starting to see the slack, I have changed the design of my system. Now, I set the lab jack to work with the position of the goose neck. To go from loading mode to operating mode, now I have a spacer. I am going to try and attach a photo of this new setup

Received in good order and as described. Very expertly made. Smooth action.

Très solide

Es de calidad, buen precio y me gustaron los materiales, recomendado

It did everything in every the add said

This seems good quality to me. Robust little unit that won't fail with first use. Issue I have is, when trying to raise the unit while supporting any weight, the turn knob, which is wound onto a left hand section of thread on the screw rod becomes undone. This is because the rest of the raising screw is right handed, meaning you must turn clockwise to raise the platform. This however is the direction you turn the knob to remove it from the device. So, you see, trying to lift the platform undoes the knob. There is no way to lock the knob tight unless you find an additional left handed lock nut. You try and find one of those! The good thing about this is, when lowering a weight, the knob gets tightened. Not sure that suits me though. Will continue to try and figure out a 'fix.'
