Bertschat Heated Fingerless Under Gloves - Dual Heating

Same glove as in the post, just with a more realistic pic.
So based on the initial search I got these.
Pros
- Quality feel
- Top and bottom heat independently adjustable
- Heating is concentrated in fingers, exactly where it's needed most
- Decently warm without power too as they're pretty windproof
Cons
- Expensive
- Outrageously prized extra batteries
- They're 7,4V with a some kind of barrel connector. Maybe it would be possible to use third party batteries?
- Battery sits a bit awkwardly under your wrist when your hands are on a desk. Extension cables are sold though.
- A bit on the stiff side, but not too bad
- Colorful LEDs always on in the controller bit. You may wish to hide them in your sleeves
- The controller bits aren't mirrored for the other glove. I.e. the button closest to your fingers controls palm on the orher glove and backside on the other. There are icons though
Verdict
Certainly above average but I'd still love to find a better pair.
Other models
They have single side heated model as well, and also a heated deskpad. Haven't tried either.
