They do not. It was suggested that ones with flavour containing diacetyl could cause popcorn lung. However, cigarettes contain a lot more diacetyl, and popcorn lung is not one of the many health risks of smoking. There is some anecdotal connection between diacetyl and popcorn lung, but far from a scientific consensus.

Thanks! Sorry, forgot to make sure the links to the model was posted. Now they are.

Have a K3 Pro at work, and I think the K8 Pro feels a lot better, especially with the 3d printed case. Because of the reduced travel I keep bottoming out the keys on the K3 which does not feel like it is good for my hands. Also tried o-rings, but they don’t work the same way as on a normal profile keyboard.

The V-series is a lot lower, and if I knew about those from the start I’d most probably just get one of those and skip the bluetooth.

I did not, it is still in its original case. In the new case there is a holder for a cylindrical li-ion battery. Have not dared trying it yet, though, but pretty sure it will work.

Ouch… Personal phone number exposed on Google Play? Not good. If there is not a cheap and easy way for me to get a second phone number I guess I am out. Have seen it coming for a while, Google Play is no longer a place to be for indie devs.
