I bought this on Amazon in 2009 for $41, this was when I was reeling from the housing crisis and underemployment. I was trying to start a mobile computer repair business and canned air was expensive and the reversible-flow vacuum I had to blow out cases was cumbersome to say the least. I mention this for two related reasons: First, because you should understand how expensive this purchase seemed to me then. 2009 was the first year in a decade I made less than $20k. Second, because this beast is currently listed for $113, which probably seems like a lot. I was surprised a bit myself. So, I can't say if it's worth you to you, but I will say that if this thing ever dies on me (before I do) I will gladly pay the asking price. For the money, this is far and away the best purchase I have ever made in my life. Seriously. By way of comparison, I still have my Stainless Seiko watch I bought 30 years ago -as unfashionable as it is now- it still looks and works perfectly, but that was $300. Anyway, about the vacuum, that is not a vacuum: I lost all the little accessories that came with it except for the restrictor/concentrator cone thing in my pictures. That thing blew off a few times in the beginning and I worried it would one day be sent at hyper-sonic velocity into a computer component. But once I jammed it down really hard after allowing a securing layer of grime to developed through my complete lack of maintenance, it stayed put. I had to take it apart maybe 7 years ago and tighten the nuts that hold the handle on (the handle had been slightly wobbly for a couple years at that point). Every now and then when I remember there's a filter on the bottom, I clean that. And that is it in terms of problems or maintenance. The significance of that can't really be appreciated without understanding how much I use this thing. I got out of the computer business (forever -I don't tell anyone I meet now that I know anything about them and I exclusively use laptops personally) so blowing out computer cases isn't on its resume anymore, but it gets used for everything else. I have a nice air compressor that I've had for a decade and it has literally never been used to blow anything out, just to power tools. I use this to clean my AC filters, other vacuum's filters, to blow stuff lodged into crevasses when cleaning. I am struggling to give examples that give scale to the uses I have found for it. It is incredibly powerful but is still gentle compared to, say, a pressure washer. I keep it in the most prominent spot in my workshop or in the cupboard under the sink in the RV when I'm on the road. My review seems like it's just going into the nearly infinite pile of other glowing 5 Star reviews, but I dumped on several products on Amazon recently and felt this could balance me karmically. Note though: if you do use this on small fans like those in a computer case, use your finger to lightly put pressure on the blades to keep them from spinning up too fast, it can tear up the shaft if you let it rip.
