My first venture using this "stuffer" was awkward. The base anchoring set up is unstable. I used both the suction pad and the clamp. Yes, it held securely to the counter, but it is a center pivot point when cranking the handle. I will experiment with a more secure anchoring set up.I made 12 pounds of pepperoni. It required filling the tube 4 times, so it's not a "5 pound" unit, more like 3 pounds per run.Overall, using this stuffer was easier than using my old Hobart grinder/stuffer, but it did not save any time. If it had a good stable anchoring system and held a full 5 pounds, I would have rated it 5 stars,I use this for stuffing venison summer sausage. It works well and can stuff sausage very quickly. Unfortunately it has corroded quickly after the first use. I believe it is some sort of zinc alloy (pot metal?) and it has a black type corrosion starting over time. It is not a major issue as rubbing it with a food grade oil before use will take most of the corrosion off, but it is annoying.I have had a production level sausage stuffer in the past and made large 50lb+ batches of salami and sausages. A good stuffer is essential. I lost that stuffer and hadn't bothered replacing it for a while because I wasn't making sausages, but recently started back up on a smaller scale for homemade sausage nights for dinner. I didn't want a big stuffer again, at least not right now, so this seemed perfect. Take this review from someone that has stuffed a lot of sausage. (cue inappropriate jokes).The first use I didn't have the section lever pulled the right way and it kept slipping. I thought it was just poor section. Also, It was very hard to unscrew one end of the tube in order to clean. I had to bang it a little before twisting with all my strength and large pliers to get it loose. After getting it off it was easy to clean.Second time using it, I did the suction right and it stuck like a rock. No movement while I cranked it. Worked great. Very good little small batch sausage maker.Overall glad we got this. Great price and good quality. Will get the job done for small batches.After washing it, make sure to dry it completely to avoid rust.Tubed did not fit a 21mm casing. Was able to use larger casings.The amount of meat that builds up behind the plunger face is not good. I had to take the unit apart mid-stuffing to clean it all out, and some of the meat picked up oils or something and was black so I had to toss it.Not a bad starter sausage stuffer, but if I continue to stuff my own sausages I'll be upgrading to a much higher quality unitThis sausage stuffer works pretty well. The only downside is there's a limited size of the barrel so you have to open it up and stick more meat pieces inside after just a 1/2 meter of casing is filled. So for 5lbs of sausage and 3 meters of casing I have to refill for about 5 times. You got the idea. If it's an open ended stuffer, you don't need to unscrew the lid and wind back the handle to fill in the meat. But it does a fine job sending the meat into the casing if you do it right, after a few tries.A great addition to the Homemade Sausage arsenal. The suction pad does not work very well and the clamp is not practical because you cannot secure the device sideways and then turn the handle. The clamp only works if you secure the device to the counter top and have it at an angle away from you whilst using your belly to stop the stuffer from rocking side to side whilst the 1 hand is turning the handle and the other guiding the sausage casing.
