I wanted to update y'all regarding my experience with the super lifter 2 since no one here seems to have had any experience with it.
In Short: TERRIBLE - lifter not as advertised.
Longer version:
While some measuring was needed for the install I found it to be relatively simple to install - that was the easy part. Once installed it completely failed to function as advertised.
All documentation available about the lift states in the operating instructions that "The cover should not touch the ground" in the open position. And that was the precise reason I chose to purchase this lift as I have no ground below where the cover would be in the open position (the tub sits at the end of a deck).
Once installed, I used the lift to open the cover and lo and behold the entire thing wants to fall off of the deck in the open position. Not only does the lift not perform as advertised but its design also was successful at ripping the stitching on my cover. Upon contacting the company, Ideal Spa Covers, and sending pictures and detailed information over a period of time they instructed me that I "Discontinue use at once as it is dangerous. Thank you".
They went as far as to confirm that I did indeed install correctly and the reason it wasn't functioning as expected was that it needed to come in contact with the ground.
So now I have a newly purchased lifter that is non-functional and tears in my cover because of it and the company Ideal Spa Covers will no longer respond to any of my correspondence.
At least you, the reader, can benefit from my experience and be sure to not purchase or recommend any such product from Ideal Spa Covers.
