Up close with new Moto Mods: The Livermorium Keyboard Slider and Lenovo Vital

This new Moto Mod adds a physical keyboard that slides out from the back of your phone.

This mod magnetically snaps onto the back of any Motorola Moto Z phone, like the Z2 Play or the Z2 Force.

The Livermorium mod gives you a full-five row keyboard like on Motorola's old Droids, but it doesn't have a naturally ergonomic, staggered layout. I used the Droid 2 and Droid 4 for years, but my muscle memory didn't kick in at all.

The individual key feel is on the money, though. Droid all the way. 

And get this: the whole keyboard tilts up, like on HTC's old phones. It's adjustable to any angle between flat and 60 degrees.

Here it is open flat.

At an angle, it doubles as a stand for watching movies.

Here's the slider mechanism. Pretty cool, no?

The big downside: It nearly triples the thickness of your phone.

Here's a comparison between a Z2 Play with a Turbopower battery pack and a Z2 Play with the Livermorium keyboard mod.

But you haven't seen bulk until you've checked out the Lenovo Vital mod -- which is honestly pretty cool despite that.

It can measure your vitals -- thus the name -- with its built-in blood pressure, pulse and temperature sensors.

Diagnosis incoming.

Time to take your temp.

It might look ridiculous on your finger, and it might cost nearly $400...

But the companion app does keep track of all the data for you.
