I have used many fluid extraction devices. They are always 1 of 2 different kinds: manual pump, or pneumatic pump. Each is useful in its proper place, obviously.This one? Why, this one does BOTH. If you're in a situation where you can hook up to an airline, then you can suck whatever right out without barely lifting a finger. If you're in a situation where you're far from an airline but you still have fluids to extract? Well by golly it'll do that, too, because it has a manual pump as well. I don't think I've ever seen a fluid extractor employing both methods. This is extremely handy in so many situations. Plus, as a side benefit, if the manual pump ever fails or breaks or something, you still have the pneumatic function until you get it repaired or replaced.And it's not just good for oil changes. Transmission fluid, differential fluid, transfer case fluid. you can do all those with this. Any fluid, really, if you can reach it with one of the tubes, you can suck it out with this.This is my new sweetheart in the garage. And it just so happens I have some transmission work coming up this spring, so it'll get some good use. This is a very handy fluid extraction pump, folks. Manual or pneumatic, it goes both ways. And the reservoir capacity of 2 gallons is plenty for just about any extraction that I can think of. Perhaps only diesel mechanics might have to empty this halfway thorough a job. I can't recommend this enough. You just simply want one of these, whether you're a home mechanic or a pro, you will find this very useful. 5 stars.

First of all, this thing came packaged like it was going to be hot dropped from a c-130, quite impressed with the level of bubble wrap and measures to keep it well protected.It’s absolutely loaded with features, manual pumping, pneumatic connection with a valve, durable and wire reinforced hose, extended tube to hang the hose from, extra gaskets, a multitude of differently sized extractor hoses and fittings and a pressure relief valve. It has a strong, wide base to prevent tip overs, holds 2 gallons of fluid and an easy to carry handle.This is exactly what I’ve been needing and I can’t wait to put it to the test. Will update with any issues experienced in time but it looks like it can hold up to everything I throw at it. Used it to pull up some water to check for leaks and it had none.To note, this extractor has a warning to not extract fuels, so I imagine the seals won’t handle anything too corrosive.

I've been eyeballing one of these vacuum extractors for a while and finally bit on this one. I was just tired of needing ramps and a roller to change my own oil or someone's help to bleed brakes, you know?The good:1.) It works! That's the most important thing. It works *great*. I tested the manual mode for a bit and determined that it works well enough, but the air-driven option is *much* superior. If you have a compressor, use it. Your arm will thank you.2.) Onboard storage for the tubes. Makes it easy to transport and organize.3.) Multiple tube options. My advice is to use the largest tube that'll fit. You'll save time on extraction.4.) Extra gaskets for everything! Speaking as someone who's had to haunt the hardware store aisle with a piece of equipment in the past swearing and trying to find something that works, that's a really nice touch.5.) The tubing is just generic tubing. You can replace it with the appropriate size/material if you need to with a trip to the hardware store/ordering online. (You can also make them longer, if needed.)6.) A minor thing, but... the smallest extractor tube comes with a little piece of wire with a loop at the end in it. I couldn't figure out WHY until I spent a second and realized... the tubing is so small that it would be easy to bend/kink it by accident. The wire is to keep it in good condition until you've got it in place! Then you pull out the wire and attached the hose from the extractor body.7.) The main hose has a little hook at the end of it to allow it to hang on either the pump handle for movement/storage or a nail or something to allow it to full drain into the cylinder body.The bad:1.) The tubing is held together with a friction fit. It's easy to pull apart by accident, especially if you're pulling out warm oil (which is how you SHOULD be doing it).2.) There's no holes or anything at the bottom of the storage tube on the side, which means any fluids dripping out of the tubes is going to pool there. (Easy to solve with a drill, really. Not worth marking down a star.)3.) Manual mode is a *chore*. It's a lot of volume to put under vacuum by hand.4.) Emptying the cylinder is... messy. About the best way I've found to do it is to pull the hose off entirely and pour the contents out through that. It would have been nice to have a small port at the bottom instead. I may look into options to add one.5.) The included brake cylinder bleed line doesn't fit in the storage caddy. Thankfully, you can coil it up and hang it off it, but still.6.) A very minor one: the onboard storage is actually two pieces. One is already attached, but you have to install the second. It may have just been how mine was packaged, but that second piece went AWOL until I found it on the floor a bit later.7.) Instructions are... not super great, honestly. There's a little brass plug with a couple gaskets on it in a storage hole in the lid. What's it for? No idea! But it's there! There's a couple extra holes around that plug. Why are they there? No clue! Honestly, it feels like someone copied a design... but didn't copy the instructions with it.All that said... to repeat my first point: It *works*. I was able to change my oil in nearly no time at all, without needing to crawl around and get oil all over my hands/garage floor. Zero serious complaints, five stars.
