I have been trying to do some research on these and I have found many different variations from cheap bilge fans to companies selling something that looks and sounds believable, but I'm still skeptical. Any thoughts or actual experience would be great. 5-20% HP gains for under $300 sounds great, but I have been burnt in the past. Here's a couple of links, if you want to see for yourself.

Not sure what kind of car you have but I checked out those products and I would highly advise you to stay away from them for several reasons:

1. They are electric, which presents a few problems, one being an extra load on your vehicle electrical system, another being they are huge electric motors that could also possibly induce noice into your system, and because they are electric they will wear out much faster than the typical mechanical superchargers

2. They claim up to 2 psi of boost and 5-20% HP, WHOOOPEEEE, lets say you have an engine that produces 100 hp and you manage to get extremely lucky enough for a 10% HP gain, which is 10HP. 10 HP might equate to getting to that next traffic light half a second quicker, that is why the REAL superchargers provide a min boost of 6-9 psi with a 100hp+ increase, which means you will be zipping to that next traffic light quite a few seconds faster and pay $3000 for it

3. If you want to $300 for some extra power you can get a 75hp NOS kit from ZEX or Nitrous Express, or if you want something more reliable for the same amount change your exhaust, intake, and get your car chipped.

4. My final comment and opinion on those "electric" superchargers--- You can paint a terd, but you can't polish one.

My mechanic told me, "I couldn't fix your brakes, so I made your horn louder"

I absolutely second everything ezridr says, plus a couple of additional caveats: First, the blades on most of those are made from a plastic that can't handle the underhood environment of a car. Care to guess what happens when the blades and motor mounts start to deteriorate? Second, they cannot possibly even start to move enough air to make the 5% gain, nevermind the outrageous claim of a 20% gain. Third, if you want performance gain on the cheap, ezridr points out a couple of good ways. Another is a less restrictive exhaust system. Or a half-way usable cold-air induction system. Maybe a bigger bore intake body. The point is, there are a lot of different mods that will give you a useful gain that is safe and proven.

Well, I agree with you guys. I was just wondering what some other opinions were. I drive a 95 Civic EX, full cat-back exhaust, short-ram intake, DC 4-2-1 header, Jacobs Ignition with MSD Blaster 2 coil, B&M Fuel Pressure Regulator, and a Zex Nitrous kit currently setup for a 55 HP shot. Other then doing an engine swap or adding a turbo to my SOHC, I'm kinda at a limit as far as power. And I really don't want to rebuild this engine. I'm just looking for ways to add some more power to my current setup.

maybe bolt a leafblower on to the intake and have it rev with the engine for the boost.. nahh just kidding.. although it would probably work haha

They are absolutely useless, if you are looking up stuff for performance do it the right way and get a turbo. Do you have the d16z6? Check out this forum Honda D-Series or this link Home Made Turbo

Well lemme join the party here. Anyways that's not true. The electric superchargers you see on eBay are bilge blowers, eRam is a remote control airplane's ducted fan engine, and we actually are legit. The owner of the company put in a good 120k or so to get the product we currently sell. The casings are made of polypropelyne plastic made to withstand 650 degrees and the fan blades are NOT plastic. The whole fan is 1 piece stamped aluminum. The only thing that deteriorates at all are the two brushes in the motor. They last only 2 to 3 thousand hours. Now you're only using this at WOT so it's hard to even imagine how many miles you will go till they need to be replaced (35 dollars a pair). Check out how much air your motor needs by using the formula (RPMs x displacement in cu. in)/3456. The single turbo provides enough air for most motors. Gains have been up to 45 with the twin and on average 10-20 with one. This kit was made mainly for people who have no type of supercharger or other turbo kit available. For people that do have a forced induction system already it does lower the turbo lag.
