Update 02/04/2019After a little less than two years this Powermatic I+ is all but dead, far short of the original Powermatic's lasting over four years and being replaced only because of normal wear. The reason is the one-plus has a PLASTIC case and internal parts instead of steel.There's just not much more that I can say in my disappointment other than it's highly unlikely that I'll ever buy another one. It's such a shame when quality is degraded in the upgrading any quality item.Update 03/15/2017:With my Powermatic I showing signs of wear after over four years of making one or two packs of cigarettes each day I decided to order a new one. To my disappointment, I had to return the first new Powermatic I+ because of an apparent timing problem that was causing the injector shaft to hang on the cutter/compressor, but then after receiving the second one I've been fairly well impressed. My old one was never so smooth, so they did make improvements during the four years. The cigarettes are more uniformly packed too, so I really like it.As far as my old one, it still makes a good cigarette, but based on the smoothness of the new I+, my guess is that it will last even longer than than the old one before showing any wear.----------------Just so you know that I'm not new to the RYO arena, with my wife smoking too, I've been averaging two packs of king size cigarettes each day for over eight years now. Of course one of my reasons for getting into RYO was the tax attacks on cigarettes, but my main reason was to avoid the (who knows what) chemicals, especially after the "fire safe" mandate.In the beginning I bought a Top-O-Matic (T1) because it was available at a local tobacco shop. During the four years plus that it took me to wear that machine out I tried each and every machine that the shops in this area had set up for demonstration, and I never found one that offered any major advantage over the old T1, so since my first T1 had lasted for over four years, I played it safe and replaced it with another new one. Now at the end of another four years that second T1 is very loose, pretty well worn out, so I decided to look for another replacement. (Note that I've never broken a machine, so both of those old T1s will still make a cigarette.)I never had any interest in the electric machines over just being anchored to an electric socket, and I definitely didn't want one of those older auger type machines after seeing videos of them grinding up the tobacco. I don't doubt that major improvements have been made in all of the latest electric machines, but still, they all require that electric socket.After hours of researching, this "Powermatic I Manual" machine was the only one that captured my attention, and then after reading the review and watching the video in the RYO Magazine web site I had to have one. The following may be more than anyone needs to know, but I think it's important enough for me to type it.The titanium cutter/compressor will handle virtually anything you can pack into the chamber, effortlessly, but be aware that packing too much tobacco into the chamber WILL jam the injector, and I have no doubt that trying to force the injector through will break it the same as with any other spoon-type machine. NEVER apply excessive force to the lever! The warranty does not cover any kind of damage caused by missuse.Also titanium is a very hard metal, meaning that the cutter/compressor will probably stay sharp for years with very little wear, but any foreign object will 'probably' chip the cutting edge. Check the tobacco closely, removing the stems and making sure that nothing goes into the chamber other than tobacco. The tobacco 'dust' can be mixed with stranded tobacco (it's all tobacco) so as to not waste it for as long as care is taken to not jam the injector. (The dust will jam the injector unless it's mixed at least 50/50 with stranded tobacco and is NOT packed into the chamber.)Expect the injection phase to 'BANG' against the stop, especially right at first. That is the ONLY thing about this machine that I had any concern about, and even that no longer concerns me after understanding that it's designed to inject quickly, with speed, to insure the tube is filled completely with perfection. That bang seems to be growing less evident with use (a break-in period maybe), but it's doubtful all of it will go away because of the design. Apparently it doesn't hurt anything anyway, so just ignore it.Finally, since this machine is new to me I have no way of knowing what the life expectancy might be, but what I do know is that it's so far advanced above all other manual type machines there is none to compare. I wouldn't sell it back for twice the amount I paid if that meant doing without it.Happy smoking! (Until the federal dictators make smoking illegal.)
