I am stunned to hear micro USB is rated for that many insertions. The implementation must not live up to the standard. In my experience, anecdotal, I know, microUSB is the most unreliable of all the USB form factors I've experienced. Bad connectors on cables, and ports that regularly fail internally (not levered off the board.) I have considered replacing ports with miniusb, or a tethered B port because micro has been such an utter failure on so many of my devices.

Fail on history: It wasn't the Sensor in 1990 that introduced the 2 blade cartridge, it was the TRACII in 1973, followed by Atra, and then Sensor. Meanwhile, Shick had their own inventions, such as the Tracer.

Further, IP was such an issue that it caused King Camp Gillette to lose control of the company because his competitor held the patent to his newly invented blades. It was going to be settled by buying the competitor and giving the competitor's founder non-voting shares, but it came out in due diligence that Gillette had been over reporting profits. American Safety Razor executed a reverse takeover and kicked Gillette out... and it all began with an IP failure over blades.

Sesame uses a CR1620 battery.

The range is configurable. One of the things this adds is a button. A button-press can be required to unlock the screen in addition to being nearby. It's very reliable.

I don't have an eject key on my Mac. No DVD drive, no eject.

It goes on the same keyring as my house key.

Good comments.

Here's a photograph of fitbit next to Sesame. They're about the same size.

iPhones have this habit of running out of battery. That could be inconvenient. The battery in the key fob probably lasts on the order of months because that's its only purpose in life.
