Works pretty well.  I have one.  But is is badly pitted with rust after
only one season.

Here is something that might help cut down on the corrosion.

Get a piece of either Magnesium or zinc. A hunk at least the size of a
chicken egg. Also get  a long piece of copper wire. Connect the wire to the
metal egg and to the metal frame of the lift. Be sure that you have a good
electrical contact at both ends - either solder the wire in place, or
clamp in under a screw or bold of some osrt.

Now just let the metal egg dangle in the water and LEAVE IT THERE.
This tends to transfer the corrosion effects to the metal egg from whatever
it is hooked to. When the zinc/magnesium is eaten away, just replace it
with a new piece and you're back in business.

This works quite well on boats in salt water, so it should help in your pool.
At least, I think so.

Bill.

This has the added benefit if dosing your pool water with zinc oxide, so 
instead of taking those supplemental zinc tablets, you can just drink an 
ounce or two of pool water each day and save on the cost of vitamins and 
minerals.  

Seriously, you don't want that stuff in your pool.  The zinc works because of 
an electro-chemical reaction.  It will actually work better if the zinc is 
in direct contact with the metal you are trying to protect.  If you need to 
prevent the rust, bolt or otherwise attach the zinc to the metal.  If you 
can, put it where you can't see it - like inside the tube for the lift, 
because oxidized zinc looks really disgusting.  Put it where it is least 
likely to get wet and you can minimize material loss.  As long as there is 
some unoxidized zinc left, it will continue to work, so you should only 
need to do this once.
