I bought these to provide support to a wooden deck/porch at my house. These smaller ones do not have a way to increase their height under weight of a joist or beam. I had to raise the joists into level using a bottle jack and then put the jacks in place - much more work than I was anticipating. It looks like some of the other/larger models do have capability to insert a rod into the screw and turn them in place, raising the jack into place. If you;re looking for something you can raise into place and level, these are not for you. If you can raise and level with other capabilities and just place the standard into place to hold it, they work.

Il est impossible de pousser quoi que ce soit avec ça. Ce ne sont pas des crics, ce sont simplement des pattes ajustable. Extrêmement déçu de ce produit.

They are ok for light lifting. Not as heavy duty as I thought they were but usable

Limited to two sizes, in order to start raising it has to be screwed on to the wood on top otherwise the jack itself will start to turn with pin.

They're okay, but the tops are welded fixed. And you are unable to jack the top plate is in a fixed position

These came up just short of my need and I wanted to exchange and pay offense for next size up. Return shipping is not worth sending back. Get it together VEVOR! The prices are not so much lower that it’s with buying when amazoo has a better return policy. You are losing my business

I ordered some spare parts, but they haven't been able to ship them for a month now—and they won't refund my money! I do not recommend getting involved with Chinese goods of such mediocre quality!

DO NOT ORDER FROM VEVOR.com. If you ever have issues with the product, they will try their very best to claim that it is working properly and make you jump through hoops (e.g. make video, pics, delay responses) to deter you from returning it. Does not matter if this product is good or not, the fact is that customer service is really bad, that should stop you from doing business here.

The middle pole on 2 of 3 were damaged and they wouldn’t turn or come out. I contacted “customer service” they took the information and never got back to me. I’d give 0 stars if it was an option …

They sent me a broken one with a fixed one in each pair of 2. The broken ones were either spray painted closed, or otherwise not movable..Of course they wouldn't be able to sell on Amazon or any other site. Very bad business practice to send your customers damaged goods that you couldn't sell somewhere else!! The ones I bought from Amazon were ok, and even cheaper.
