After reading the reviews, which were mostly not very favorable, I figured I would give it a try anyway since loading my pistol and rifle took so much time. I have the Umarex Smith & Wesson M&P pistol and the Crosman M4-177 rifle.My speedloader came factory sealed in a package that you have to cut to open. After opening the package I look at the thing and at the bottom (magazine loading end) I see what looks like a steel bb, but I say to myself, it can't be a bb this thing was in a sealed package, so I try to push it into the loader, but it does not move much and I did not want to break the thing in case I had to send it back, and pushing on the plunger on the speedloader did not move it either. So I put the adapter for my pistol (it comes with four adapters for various pistols) on the speedloader, filled it with bb's, held my magazine against the bottom of the loader and pressed the plunger (you have to press it pretty hard, but do not try to force it if it feels jammed) and the bb's went right into the magazine, about 5 or 6 at a time. You kind of have to twist and shake the loader to get the bb's into the dispense area of the loader and when you have done that you just keep pressing the plunger until the magazine is loaded. You do not have to lower the spring in the magazine, the speedloader just pushes the bb's right in.After loading the pistol I went to load the rifle (It just has a 3/8 inch hole in the side to drop bb's into) , I took the adapter off the speedloader and just put the loader against the hole and pressed the plunger and bb's went right into the rifle's reservoir. It holds 350 bb's and did not take long to fill it.This speedloader saves a lot of time and works very well. The plunger is plastic though and you have to be careful not to put too much pressure on it if it seems stuck. If the loader does feel like it has jammed just shake it or bang it against your leg or something that is not too hard to free it up. And by the way, the loader apparently does come with a bb in it, at least mine did. Maybe my loader had gone back to the factory if someone returned it and the factory properly sealed it back up. In any case it looked brand new and worked as it should.Good shooting.Update: Jan. 3, 2013In case any of you thought I was nuts for giving this thing a good review, you were right. Umarex should be ashamed to sell such a poor product. After using it (or attempting to) for many magazine reloads I find that it jams much more often than it loads. I am only surprised that I have not broken the plunger yet. When it works, which is rarely, it loads well, unfortunately that is not often. The internal mechanism on this thing is obviously poorly designed and the company should recall them, repair the problem, and send us a workable product.I lower my rating to one star.

Although a good idea in theory, it doesn’t work as designed. It is fragile and requires a lot of work and patience to operate. To add insult to injury, it frequently jams, and ultimately ended up with a broken plunger and a trip to the nearest trash can.PLEASE stop selling this poor excuse for a speed loader!You’re better off using a plastic straw or a repurposed ball point pen, than this piece of junk!

I have had my speedloader for about 3 months now. At first, I was like some of the other reviewers. It was more of a hassle then it was worth. It jammed on me all the time and seemed very fragile. But I planned on buying extra clips, enough to last 1 co2 cartridge, which turned out to be 9 clips total. I was not about to manually load them. I even bought 2 more loaders so I have not ever have to do so.I kept playing around with the loader until I learned how to use it. I broke it twice but was able to "crazy glue" it back together and keep it working. Now I do not have any problems at all with jamming and man, does it save me a bunch of time. I have ran about 12,000 BB's through it and it still works fine, "crazy glued" and all.A person has to remember 2 things and that solves most of the problems. 1st is to shake it between clips to preload it. The second and the most important is to place the clip BB follower in the load position. Not doing so is how I broke it and also was the reason for it to jam up.I fully agree that the loader should come with better instructions and a very clear warning about what will happen if the BB follower in the clips is not placed in the proper position.

This has definitely worked for me. I use it to load my Beretta M92A1 Full Auto magazines and it gets the job done in literally seconds. I just take the squared corner of the plunger tab to push down catch of the mag, then align the outlet hole to the mags inlet hole and push the plunger down. Takes 3 pushes to fill each mag. Couldn't be easier!No need to use my thumb nails or anything else. Once in a while I misalign and drop a couple of BB's, but compared to loading 18 BB's by hand each time, I'll take that any day! Just pick up those dropped BB's, put them back in the loader, and ready to go again.I use it with my Sig SP2022 as well and it's just as fast.My only complaints about this are:- Shaft of the plunger feels weak and flimsy - needs to be thicker- The plunger lock comes unlocked too easily - just a slight touch and the plunger pops up again

The entire gadget is made of plastic, and the loading mechanism into the gun magazines isn't very smooth, and I actually damaged mine's by pressing on the handle a bit too hard when loading the bullets. It's still usable, but knowing that I have to be careful when loading bb's isn't the best feeling when you're trying to enjoy some light airsoft gun.

Lousy. Jams most of the time with Umarex steel BBs. Occasionally works if I keep tapping on the side and rotating it. But even then it only works about 10% of the time. Don't waste your money!

Loaded first magazine fine then decided to start jamming. If you pressed too hard you could damage the BB’s or break the speed loader handle. It would NOT stop jamming after first use. It’s honestly faster to just hand reload then use this. Almost a complete waste of money (it at least worked once).

Très beau produit de bonne qualité.Pour l'instant rien à dire sur celà. À utilisé avec plomb BBs acier et non avec recouvert de cuivre car comme toute chose avec ceux en acier rien ne s'encrasse!! Fonctionne très bien alors rien à dire !!!

All it does is jam constantly... You're actually faster in loading a mag through the loading port with a conventional bottle and loose less BB's that way too. So the only point to this product is you wasting your money really

Overall build of the loader is made of bulky but weak feeling plastic. Works well and can load 3-7 zinc coated BB's a pump. I do recommend and So far the best speed loader on Amazon

I have put thousands of rounds through with no jams or problems but I do lubricate my B.B.s with some oil so that may be why it doesn’t jam like other people have claimed

Jammed up very often.
