Second I've had. Works great

What a pain!

Comes in a million pieces and instructions are terrible. Save your money.

Plastic Junk

Apparently it used to be made out of metal, which led to many issues ??? So now it's made out of cheap plastic which leads to the angle arm getting warped by the sun, which in turn affects the shock arm rendering it BROKE and useless! Lasted less than 4 months in the PA sun. Awaiting a new shock, but have been informed that the warped angle arm will cause this issue again, yet no replacement being sent for the angle arm.... save your money & your sanity or you will be blamed for causing the angle arm to warp by not operating the shock correctly!! We are 2 adults - careful & responsible, with knowledge of engineering & mechanics.

Just what I was looking for.

We have a partially buried tub with a stone perimeter ""deck"". This is exactly what we needed.


I had read other reviews that said the directions were less that good. I concur. It took quite a bit of time to assemble and in the end, as we feared whole assembling, the system wasn't going to endure the process of raising and lowering for long. The main unit is made of a hard plastic and just will not hold up to the demands placed on it. It's our intention to return it as soon as we unbolt it from the deck. Disappointing. We now have 10 holes in a brand new deck.

Plastic gets heated in the sun, becomes soft and bends

You tube shows a metal bracket, that's not what you get. The shock strut was so stiff that it pushes itself out of the ball and socket. The plastic gives when hot outside.

Replaced after 12 years

The aluminum hook that captures the center of the spa cover could be stronger. I have had two fail at this point.

Nice lifter

Once put together seems to be working well. Agree with the other reviews on the instructions - really could use a rewrite.

Nice lifter. Would recommend it

Good lifter - works well so far Installation not too bad - but instructions are weak The nuts and bolts included were indoor zinc plated - seems that would rust quickly. I went out and bought stainless steel bolts and screws. They also included plastic caps for the nuts - which seem they would come loose and expose a sharp edge. I replaced those with stainless steel acorn nuts

I like this lifter.

I was designing a lifter and this one was close to my design so I decided to use it. It works very good however I couldn't get it to work well as per instructions. My tub has some rock like designs all around that stick out past the sides. This made the arms stick out far past the sides so I swapped sides with the bases and that allowed the arms to set much closer to the tub. The cylinders on the arms want to lift the center and was stretching my cover in the middle and was pulling the seams apart so I added small budgie cords to hold the cross bar down and the problem was solved.
