Great for the price, works as it should

Gonna give this one 5 stars due to the price being a good all-in price and actually working better than I expected. Not a lot of reviews on this particular listing but it's the same as many other similar tools with a few differences (on the positive side) from what I found on reviews of others. That is, I read reviews on other similar-priced ones that had various deficiencies or omissions. I didn't find that to be the case here. Examples...1. Other similar kits may come with odd air fittings or not the right ones for North America, or don't come with a second fitting. Not true in this case. The [air inlet] fitting that's attached is seemingly a standard "US type" brass industrial or IM fitting. I'm not 100% sure since I have a universal connector on my airline, but that's what it looks like. The other fitting (which is included) looks like a US high-flow fitting since it's about the same but has a larger diameter inlet. The fitting is the standard type of female-threaded fitting you'd find on air tools *but* the way it is fitted to the venturi manifold is it uses another adapter with male threads on both ends. Unfortunately I couldn't remove that adapter from the standard fitting as when I unscrewed it from the manifold, the adapter came out with the fitting instead of staying in the manifold. This means you'd have to grab the threads of the adapter piece and trying to turn it risks damaging the threads. I wanted to use the high-flow fitting but after realising I could damage the threaded adapter I just stuck with the stock one--again looks to be standard industrial type and worked fine.2. Many of these tools don't come with the "discharge" hose and only come with the fill hose for pulling coolant in. This one *did* come with a discharge hose which is not a huge deal but a nice addition and nice to have everything "in the box" when you get it. When I put air on it, air shot out of the exit/discharge like crazy, as expected. But I guess I drained enough coolant from the car that no coolant (liquid) expelled. So really I didn't need the hose on the first car I used it on but better to have it than inadvertently spray coolant all over the place.3. A lot of other ones near this price point seem to have a cheaper gauge on them; I bought this one specifically because it has the rubber guard for the gauge, and it does indeed come with that as pictured. Only thing is I wish the gauge had different units--it has only inHg and cmHg--would have preferred one of those be bar or psi, but is what it is. Can't complain too much since it worked fine and has appropriate green/yellow/red colour coding on it.4. Everything fits in the case fine. Read reviews on others where the case is substandard, things don't fit/fall out, etc. This one seems good! It's red as pictured as well, in case anyone was wondering.First use, I used it with the smallest adapter on a VAG vehicle (Audi Q5). The adapters seemed like the next one up was "too large" and the smallest one "slightly small", but the expansion of the rubber from tightening the main knob thing, proved to make the proper seal as designed--held vacuum without any issues.Only other thing I'd note is this thing takes a lot more air than I expected. I have a smaller 4.5 gallon "high performance" type compressor (200psi tank, 5.1 SCFM @ 90) and it was basically just barely enough to use this well. I wouldn't try to use this on anything smaller/lesser either in capacity or flow as you may not be able to pull enough vacuum. If you have a smaller compressor, you'll also want to open the valve on the unit and then connect the air so you don't have any "wasted" air not pulling vacuum like would happen if you connect the air then turn the valve. Max psi on this is supposed to be 90 psi but my compressor could not maintain that output so what I had to do after a couple attempts (and not getting vacuum) is just set my regulator to like 120 and then connect it as described above--[regulated] pressure dropped immediately to less than 90 anyway and compressor kicked on in no time, so just kind of got an initial boost this way. Anyway I was able to pull the vacuum and get the hoses to collapse and all that.Closed the valve, turned off the compressor and disconnected. Filling the system after is easy peasy, works like magic, just put the coolant bottle higher than the tank drop the hose in and connect to the tool (now with manifold removed) and open the valve again and presto, it sucks coolant back into the system and you're done. Had to top up with a little more after but that was expected. All in all I was much more seamless and easy than I thought it would be.TLDR: Worked really great, includes *everything* you need apart from coolant and compressor. Highly recommend!
