They’re *really* heavy. I was legitimately surprised about how much they weighed the first time I pulled one out of a customer’s bike.
For some riders that’s an unacceptable tradeoff. For others, it isn’t. What it will be for you depends on your own riding goals and priorities.
If it’s not an unacceptable tradeoff for you, then they’re perfectly fine tubes and can help prevent a puncture from ending a ride. That said, they may make a mess and cause you to get sticky hands and/or an annoyed mechanic, depending on whether you change out your tube yourself after a puncture.

Those work great. Before going tubeless I had those on my commuter bike. Ran over a large construction staple that went in the tread and out the sidewall. Pulled the staple out and it sealed instantly. I ended up keeping that tube in for hundreds of miles until the tire wore out.

Personally despise slime tires. Very heavy and valve clogs and the green shit gets everywhere.

We have a lot of sand spurs where I live and these are great for them.

I’ve had moderate success with a ghetto version of these – remove the valve stem from a tube and stick ~50ml of stans sealant in, way lighter than the slime ones and will get you home in a pinch (flat).

They are heavy but worth it for the staples or sharp things on the rode, has helped seal the puncture, when in inflating you need to have the valve facing down at the top of the tire so the slime goes to the bottom or else it clogs the valve,

What I have found with slime is when it seals, the seal still weeps. I havent used them in several years though so maybe they are improved.
Also the slime (or any sealant) interferes with tube patches if you are doing road side repair. May not be important for your use case, but can make a different during things like long distance unsupported touring and the like.

Aren’t those extra viscous? It might plug up the valves. Also it’s extra messy if you get a puncture. You still have a tube and now sealant mixing with tube and inner tire if you get a puncture.

Flat Out is better, but with either you should get a valve core remover tool and extra valve cores. If you don’t set the wheel at the right orientation, the leak stop liquid can foul the valve when releasing air from a pressurized tube. Replacing a replaceable valve core is cheap, fast and easy. All Schrader valves are removable. Some Presta valves aren’t designed to be removable so you’d need a new tube with those.

They do not work and they are very heavy.

Ive got a surf bike that is a total beater, rusty as hell, will melt into the ground eventually. I fully replace the v brakes and driveteain with a new cheapo set about every year or so because the salt water just completely destroys them.
I pulled the cores out of the shraeder valves and put some automotive slime into the tubes. I haven’t had a flat since. They havent even lost air when sitting outside for months on end. Would I do that on any of my other bike? No. But for this bike it worked perfectly.

I just bought these and am returning them. They are SO HEAVY.

I used to swear by these back in college. I now use schwalbe tires and/or put orange seal in my tubes. Have not had nearly as many flats as I used to with these (I also ride on the sidewalk less, which I think reduces goat heads)

They’re crazy heavy and they’re actually not that good at preventing punctures. Not worth it in my mind. If you have a lot of issues with punctures, make the investment to switch to tubeless.

I’ve had them on my 29er hardtail for 18 months. Last time I swapped the tires each slime tube had at least 3 punctures (goatheads mostly) that I had never noticed. Very little weeping. Sealed up well. I didn’t even replace the tubes just put the new tires on. So far I’ve done another 500 miles mostly on trail and haven’t had an issues. That being said they are heavy and I imagine they add quite a bit of rolling resistance.

Garbage. Pay the premium for TPU tubes if you don’t want to go tubeless. They’re far more durable and a fraction of the weight.

I love the slime line of products. Mostly because, in regard to any particular product line, the products are usually no frills, in general work as described, and are usually decently priced.
I use slime 2in1 tire and tube in my tubeless mini bike tire, and I use it in my bicycle tubes. I use the stuff preemptively, and I haven’t had a flat in a long time.
Occasionally, I might get a screw/nail in a tubeless tire on the mini bike. When this happens, I’ll mark where the hole is, disassemble the tire from the wheel, and use the slime vulcanizing patches on the inside of the tire.

They likely work but they are very heavy
garbage!
