Since most people reading this are probably smokers, I will dispense with the "mea culpas" people seem to expect when you do something they personally disapprove of. :)As near as I can calculate, I've rolled over 1500 cigarettes with this machine with nae problems that weren't my fault.I've cut my smoking casts from $.25 to $.04 per cigarette.In fact, if the machine broke tomorrow, I could replace it and still have saved money. A *lot* of money. I am a professional level smoker, people. :)Some tips for you, if you are new to RYO (Roll Your Own)that have worked for me, but, your mileage may vary:Buy the machine online. locally, they sell for $20 to $40 more than from Quality.Do NOT use the powdery tobacco from the bottom of the bag. it WILL jam the machine. That "pop" you her when it jams is the (probably plastic) gears that drive the "spoon" that injects the tobacco into the tube trying to "strip". This is, from what I've read, the #1 cause of machine failure. I have never had a jam since I learned not to use the stuff from the very bottom.Don't over fill the loading tray. Over time, you will learn how much tobacco you need to pack in it. Over filling = potential jamming, and undue stress on the "gate" that closes over the tray. If the lever that activates the machine is hard to pull, you have too much tobacco in the tray. Don't pack too tightly. Read the instructions, fill from the center, and you'll consistently get a full, "tight" cigarette. Every. Time. If your fingers are less than slender, I suggest buying a $6 manual machine , and using the packing tool from it. This unit does not come with one.Occasionally, you will have some strings of tobacco hanging from the end of the finished cigarette. If this bothers you, you can get a tobacco cutter here on Amazon. I used to cut mine, and I used a $9 coffee bean grinder. From what I can tell from pictures the blades used in both look identical or very nearly so. If you do used a bean grinder, just 'bump' the switch once, then check your tobacco. The first time I used one, I wound up with a bowl of useless tobacco powder. Lesson learned. I no longer cut my tobacco. I assume with experience, that I learned something unconsciously that makes it an unnecessary step.If you *really* feel like you are wasting tobacco, go ye then to a big box discount store, and buy a hand held strainer/sieve, and you can put handfuls of tobacco in it, and sift out a lot of what causes the problem. I also put my tobacco on a paper plate, then transfer it to the machine, and over a rolling session, a lot of the junk will gravitate to the bottom. The unit does come with a nice, handy, cleaning kit for un-jamming it. Follow the instructions.If your kitchen table is not handy or appropriate for rolling, get a good quality folding "TV Table". I keep my equipment stored out of the way. I generally roll a carton at a time and can set up for rolling in about 2 minutes. I takes me, with this machine, approximately 1 to 1.5 hours to roll over 200 cigarettes. You can probably do it faster, as I don't really get in any hurry. If you can get one, a cafeteria type tray to place the machine on will help with the mess. You WILL most likely wind up with tobacco everywhere.RYO cigs are larger in diameter than ready-rolls (commercial cigarettes). You will need something to keep them in. Most of the plastic "pocket boxes" I have tried are junk. I smoked cigarettes that came in hard packs before going rogue, and saved ten or twelve of them. They've held up well, but will only hold about 17 RYO. Amazon has many choices for storage. If you look, you'll likely find something you like. A friend of mine buys boxes intended for storing crayons from a big box discount store (You know the one I mean. Don't make me speak of the devil.), and says they hold ~ 35, and have a good."seal". I bought a couple of pocket cases, Tpingfe Smoking Cigarettes Aluminum Cigarette Case, intended to hold hard packed commercial smokes, and they work well, hold 20 cigs, but, a *bit* uncomfortable in the pocket.Shop around for tobacco. you can, around here (NW LA. Louisiana, not Los Angeles.) get a 5 ounce bag for around $6, and a 1 lb. bag for about $13. Try several 'till you find one you like. Amazon doesn't sell most things that tend to kill people, but there are plenty of online sources. You can find tobaccos that approximate the commercial brand you smoked before. For instance, there is a brand that claims to taste "just like the world's most popular cigarette", or, what we used to call "Cowboy Killers". (You know the one I mean.) Just don't think you're stuck with one brand. I use a brand called "Good Stuff' because I like the way it tastes, and it has a pleasant odor when burning. It took trying several brands to find it. In a pinch, as in, I've been a poor planner, the is a brand called "American Club" that I also use and like.Buy your tubes ( the paper and filter in a single unit) in bulk if you can. They don't spoil. Locally, tubes sell for ~ $3.80 to $4.50 per box of 200. I buy a brand off of Amazon called "Zen". You can get 1250 tubes (5 boxes of 250) for between $16 and $17. Also, these tube have a "full length" filter, and some of the other brands have a shorter filter. I.e., the filters in the Zen bran are the full length of the brown-colored part of the tube, as oppose to about half that.I mention this here only because I have had people to whom I have explained "rolling your own" to comment that they could make money with it. For the record, I am NOT a lawyer or a Law Enforcement Officer or in any way connected to either, but, I pretty sure if they catch you selling cigarettes without a tax stamp, it won"t go well for you.As a disclaimer, I am not a paid spokesperson or associated with Amazon.com or any of the products I have mentioned by name in any way. These are just some things I thought that if, like me, your were insane enough to still smoke, you should know, as they might benefit you.I hope this review has helped you in some way.
