Strengths: when new, it worked as others have said--screw on to valve, depress schrader valve with red screw, pump up, and reverse.
Weaknesses: red schrader depresser develops leak around its o-ring after 2 years of use
I know there are some vocal folks on these forums that insist that shock pumps don't lose air, it's just the pressure in in the hose escaping when you take them off. They're right, when the pump is functioning as intended. This pump worked well for a few years, but now when I use it, I screw it on the valve, depress the schrader valve with the red screw, watch the pressure jump up, then slowly drop. A hissing is heard at the red screw/brass base junction. Soapy water on the variosu joints on the pump/hose reveals no other leaks other than this spot.
There's a single o-ring on the red screw that is supposed to keep the air in. I guess this must have worn out. I'll look for a replacement o-ring, maybe oversize it a little to keep it snug.
Strengths: Cheap, compact, lightweight, durable, goes to 400psi., pressure release valve, ability to seal schrader before unscrewing pump from valve.
Weaknesses: Have yet to find one.
Cheapest shock pump I could find, and it's an amazing pump at any price. The red knob allows you to depress the schrader valve after screwing the pump onto the valve. I do this to seal the pump to the shock, fill the line with the amount of pressure I think the shock has, then turn in the red knob and I'm able to more accurately check the pressure which was already in the shock.
The red button is for releasing the air pressure. Nice feature that allows you to release pressure without removing the pump from the shock. I also use it after pumping up the shock and turning out the red knob. I release the line pressure (because it is now sealed of from the shock pressure) and then unscrew the pump from the shock. This seems to make it slightly easier to unscrew from the shock valve.
This pump is also made out of quality materials. Aluminum body, brass fitting, and a stainless braided hose. It seems to be holding up great so far, and I don't see any part of it that looks like it might fail any time soon.
For the price I got this pump at, I'm amazed at how good it is. Other pumps that just screw on, pump and that's it, were all more expensive then this one when I was looking online. So if you are on the fence about getting this pump, go ahead and do it. You will not regret it, because this is an amazing product at a great price.
Weaknesses: bleed valve difficult to control slowly
One of those products where you can feel the quality in the parts used. Got it on sale for $17 on pricepoint and it's definitely worth it. Really like the two-stage valve, definitely helps control leakage when unthreading it.

Strengths: Everything, this is a beautifully machined shock pump. There isn't one flaw with it. The 2 stage screw on valve is brilliant, and nicely machined out of brass. The steel braided hose is a nice touch. Will pump a shock up to 100psi in 6 pumps or less. Max PSI is 400.
The bottom line is: There is no need for any other pump over $20 when you can buy this for under $20.
Question. How many PSI does it take to fill the shock pump when you screw it on the fork? 5psi maybe?

Strengths: Designed well
Small and light
Dual stage valve engagement
Minimizes air loss during disengagement
Swivels on the hose and chuck head
Weaknesses: Knurling on the chuck head could be more pronounced.
The bleed valve lets out too much air.
This pump is a well thought out and quality manufactured product. The chuck head is beautifully machined but it would be easier to use if the knurling was more pronounced. I found that my fingers slipped as the head approached being fully screwed down onto the Schrader valve, regardless I think that the design of the dual stage chuck head is brilliant. There is very little air loss when you engage and disengage the chuck. The pumps operation is smooth and crisp. While the bleed valve is a very nice feature it lets out too much air for fine tuning however it's easy enough to just pump back up to your desired pressure. All in all I'm very pleased with my purchase and highly recommend this pump to anyone looking for a function specific shock pump.
Strengths: Easy to use, very minimal air loss when removing. Works like it's suppose to.
Weaknesses: None as far as the actual pump. My one complaint is that the pump is only available from PricePoint as far as I know and in besides the shipping charge and additional $1.25 is added for "insurance" (kind of lame).
At this point I couldn't be happier with the pump,

Strengths: Well made. Works perfectly.
Works perfect. You thread it on with the pumps nipple retracted. Once nozzle is on and sealed you advance the nipple to expose the pump chamber to the shock chamber and pump. Reverse to take off. Works perfectly and you lose little to no air. Great pump.
Weaknesses: Small graphics, making the gauge a little hard to read.
Exposed braided stainless steel hose could scratch the frame if not careful.
Bleed button releases too much air, and is hard to control.
When I first used the Sette pump, I felt it was a little bulky and labor intensive to use, but I quickly changed my mind after using it on the road to dial in a new Manitou Minute MRD fork and Magura Hugin rear shock.
The Sette pump is a very well thought out design.
It has 360 degree swivels on both the schrader fill head and pump end of the hose, along with a 360 degree swivel on the pump, allowing the hose to be clipped parallel to the pump body for storage.
The brass fill head's threads are tapered nicely and easily threads on to the schrader valve stems without cross threading.
The Magura pump was the most difficult to keep from cross threading, as it has an angled fill head, with a quick release lever on the side.
You have to screw it on at an angle because of this offset angle design, and have to be really careful not to cross thread it as you screw it on to the schrader valve.
You have to fight the filler hose, as it tries to keep the fill head straight, and you need to bend the hose to angle the fill head and attach it to the schrader valve with one hand, while holding the pump with the other.
The Sette's fill head turns smoothly, and attaches to the schrader valve easily every time.
The Sette pump's gauge is a little hard to read, as it has smaller graphics for the psi scale than the other pumps, and does not read out below 30 psi.
The loss-less pressure release system is well thought out.
A red alloy knob on the backside of the brass fill head is unscrewed until it backs away from the schrader valve completely, closing the schrader valve and preventing air loss when removing the fill head.
It self seals with a common o-ring, which is easily replaceable should it wear out.
The red alloy knob is actually a long rod that presses and opens the schrader valve for filling, when screwed in.
When done, unscrewing this knob closes the schrader valve stem completely, while still under pressure.
Then, the brass fill head is unscrewed from the schrader valve stem.
It's a little more time consuming than the Magura's quick release lever, which does the same thing, but the Magura's angled head defeats any advantage that the quick release lever gives you.
The Magura's quick release lever feels a little flimsy, and I have no idea how long it will last before breaking off.
The Sette fill head and pressure release knob is built like a tank, and will probably last forever.
The Sette system is more time consuming, as you have to screw on the fill head and the pressure release knob, and then unscrew both, but it works reliably every time, and doesn't cross thread when attaching to the schrader valve.
After spending a few hours constantly adjusting my fork and rear shock, the Sette is now my favorite shock pump.
It even has a rubber coated gauge which none of my other pumps have, so it is designed to take some hard knocks without letting you down.
It has a plastic gauge face, unlike the others that use a glass face.
I can't say which is better; in 10 years the Sette gauge face may become scratched and yellow, but it won't shatter like a glass face if dropped.
The only gripe I have with the Sette is the air bleed off button.
It releases too much air, and is very hard to control for fine tuning.
However, it was easy to pump back any lost air to exactly the level needed.
The Magura and Wrench Force wins hands down in control of the air bleed off button.
If you're using a pump without some type of loss-less pressure release system like the Sette or Magura pumps, you are not getting accurate pressure fills.
I didn't realize for years how much pressure was lost when removing my Wrench Force pump, especially on the smaller capacity SPV and negative air chambers on shocks, giving me inaccurate readings and wrong settings.
Contrary to what some may think, the air you hear escaping when removing a pump hose is NOT the air in the hose only, but air escaping the schrader valve as you are unscrewing the hose.
You can never unscrew the filler head fast enough to prevent a large pressure loss through the schrader valve.
The Sette shock pump was obviously designed by a real bike rider, and is highly recommended.
For the price, it outperforms even the most expensive shock pumps on the market.
