This is by far the best tire tool I have used. I've tried others and they don't do the job. I have one in each of our tool bags and keep a spare set in the garage for quick access.
After one year and change these levers still get the job done. They have rescued many a stubborn tire from damage and make replacing tires easy. Leave the blue, black and coated metal levers on the rack at your LBS and get these. One exception would be those of forged aluminum from the company that starts with an L. The price is right and they do not gouge my seat bags. Good design at a reasonable price.
These work great and last maybe forever. I work at a bike cooperative and have seen people occasionally break one of these - but they are definitely the toughest levers around.
The Pedros levers are the best I've ever used in 40 years of cycling. For the 'gram counters' they're light but still very strong and durable. I was able to break one once removing a Continental tire, which always seem to be tighter than others, but outside of that I love them. Plus they come in all flavors of bright snappy colors so you look cool when using them.
I have used other tire levers, but I have yet to find any that work as well as Pedros. If you are reading reviews trying to figure out which of the seemingly identical levers to get just stop reading the reviews and get the Pedros levers.
I carry them in my bike pack for on-the-road flats. Curve down, they quickly and safely take off or put on your tire without catching and tearing your tube. It's a simple but perfect tool.
