it replaces the valve at the bottom of your tank, and plumbs into the sutff up top. Every time your compressor cycles, it pops open the drain valve for a brief moment allowing the water to squirt out.
I put one of those on my Husky/CH 7hp, 60 gal commpressor, and it flaps open on every stroke from the compressor until the pressure gets up to 50psi.. it doubles the startup time.
I haven't had a problem with mine yet. When I first put it on I noticed the diaphram chamber part was hand tight, so I tightened it, (after pulling everything apart to see how it worked..) I kind of questioned some of the rubber seals in the thing, but I'll see how it holds up. Hard to beat for $7 on sale.
You can get a timer type at WW Graingers that you plug into the wall and it opens on a set amout of time. I think it was about 30 bucks. The only problem it will drain the air if the power goes out

I removed it..
haven't been back to look for an alternative

Sounds like you had it installed improperly or it is defective??? Can you check over the instructions again? They normally just open up once per cycle.

Well, there aren't many install options. I did just like the link showed, cut the line from the compressor output/tank input to the control switch. This is the unloader line.
inserted a T, and ran the line from the drain value to the T.
I hadn't considered that the valve might be defective tho.
Try pulling the valve apart. There's a rubber disk in there that's used as a diaphram. It could be that it's not seated right. That diaphram pushes a pin that opens the valve. If it's loose, that might be whats causing it to be too sensitive. The thing isn't a diaphram like in an accelerater pump, it's just a rubber disk.
I know mine wasn't "ready to go," out of the box. I sealed and tightened all the threaded parts. I had it totally broke down - quick and easy job.
The instructions are almost useless, except for the exploded diagram. Better than nothing, but just barely. The link posted is a good one. The only changes I would make is toss the 100 psi tubing that comes with it and go with copper right from the start. If you have buy fittings to T into a metal line anyway, the 1/4" copper tubing will be right there and it'll save a trip, (don't forget the connector for the valve side.) It routes a lot better than the floppy tubing, too. Especially on vertical tanks.
