I bought these cause my grandma left me her old seltzer machine. When I was young I would visit my grandma and play with her seltzer maker. We never had the cartridges and couldn't make it work right, but I would pretend I worked in a bar and make people drinks. There were some old 50s lounge records and the turntable did work. It was like this swanky place to hang out.One time I broke off the handle and found some glue to put it back on. I never knew if grandma found out, but she would say things like, "boy, I wish we had some cold, refreshing seltzer, but it doesn't seem to be working anymore."I also use them for one of those home soda makers. It's the kind that was recalled. Hasn't blown up yet.I can't seem to find many flavors I like. We have a shelf full of the kind I don't like. It really doesn't slow down Mother. She'll drink anything.The empty cartridges amuse the cats, especially Tinker. I call him Tinker cause he knocks the empty cartridges from the work area. (Where I tinker around fixing stuff I buy from the goodwill.) Most of their electronic stuff is broken and I try to repair it. One of my brothers fixes old broken junk so I try to race him and fix better stuff.The animal shelter people came and took all my cats. They said they found 17, but I told them there were more. They looked again and didn't find any more. I was sad for a couple days. Soon realized I was sleeping better with no cats bothering me. I got back to work fixing an old stereo reciever and I heard scratching in the wall. I figured it was a rat. It kept scratching and I heard a tiny 'mew' like in Horton hears a Who when they say we are here, we are here, we are here. I moved a panel in the wall and out jumped Tinker! He must have heard me move the empty cartridges and wanted to play. I'm glad he wanted to be discovered or he could have died. I would like to thank the Leland people for saving my cat.I like how they sell these in a 50 pack. You can also buy more or less.I hope Mom doesn't call the animal shelter on Tinker. I would really miss him.It might have been the neighbor that called. She called the cops once cause she said she couldn't sleep with the cats making love at night all the time. The cops said they didn't see it and there was nothing they could do.Then the old witch asked if I could fix her tv. I said they probably don't make tubes for televisions any more and she should get a new set cause you get more channels. She did get a new tv. 52" screen, 3d, bluray and surround sound. Nicer than what I have. She invited me over once to watch a movie cause her daughter doesn't visit anymore. I never saw a daughter over there. All she had were kissy movies from the library and that's not my kind.Now I reserve all the kissy movies from the library so she can't watch them. I'll check her attic for a corpse next time I go over.

They work well

Not long ago, needed some chargers for a party that weekend, and grabbed the generic boxes that were available at the liquor store. After poorly charging the siphon on the first two attempts, I pulled out the scale and checked their weights. None had the expected 8g, most had less than half that, and a few of them were basically empty!Lesson learned. So now I'm keeping stock of these good quality Leland chargers.

The cartridges appear to be good quality, but be aware that they may be shipped in a padded mailer, with boxes damaged and cartridges loose in the envelope. (Seller for my order was Numble LLC)

I ordered these as replacement Carthage for my Kleer plunger. These are 100% replacement parts and fit into the holder as the 3 that came when I purchased it.If you are looking for replacement parts these will fit no issue... one thing I was not able to find were the paper disks needed to allow the co2 to work properly. I did figure out you can take the yellow co2 cartridge holder, place it open side on to some copy paper and tract the outside of the holder with a pen marker or whatever. Cut this circle out and it will fit in the chamber, just like the oem ones did. I find I need 2 disks to match the same force as the hem type but this is easy to find and use so I'll make 2. I hope this helps in making your decision easier

Excellent product at a significant savings from other brands. Why pay more?Update: February 28, 2016 -- After exclusively using the Leland CO2 cartridges in my Fizzini for at least a year now the latest order of 50 cartridges no longer fit the Fizzini! Yes, I've seen reviews saying these are great and some warning against use in the Fizzini. I've noticed that all recent reviews for the Fizzini appear to comment that they no longer fit properly and can damage the unit. Older reviews prior to around November 2015 are typically positive (as has been my experience). I've contacted the seller to find out if there has been a change in manufacturing or possibly a quality control problem. The newer cartridges ARE too tall for the Fizzini. Forcing them in requires prying them out with a knife or other thin metal object. This is NOT good and will force me to find another CO2 cartridge for the Fizzini. I hope Leland can remedy this problem.

The shipping package was a padded envelope. Many of the individual cardboard boxes of 10 chargers were crushed. The chargers were floating in the padded envelope. The 5 pack should have been shipped in a carton vs a padded envelope. The individual cartridges were not damaged.

what's not to like, they are soda charges
