Hands warm, but at what cost?

Preliminary info for the size of the gloves ...
I think they are already made quite large. I refer to the size M. From the feeling I'd rather typed on size "L".
My wife finds them anyway a little too big. (She has normal size M ...)

Processing of the glove, I would generally rate as good. Stable and well made. No sutures are open and no threads are available from. The palm is handy and suitable for winter sports. The gloves are good water-resistant and can therefore exist in the snow. ;-)

Included are 2 batteries and a charger. Without charging the full charge takes about 2 1/2 hours.
Are heated only hand exterior surfaces. The palms are cold in my gloves. But does not bother, because the heat quickly spread throughout the glove. The purely functional side of these gloves is described as like.
You can select 3 heat levels using the switch on the top of the gloves. (53 ° C, 45 ° C, 37 ° C)
The functionality of the switch is also good and also the service with gloves without major problems possible.

Unfortunately there's also here negative to say ...
New cost the gloves 115. (Currently 70 at Amazon).
This is in spite of everything too much. If I do not get to test the gloves, I would not spend 70.
A price in the region of 50 seems to me fair and reflects the price-performance ratio.

Unfortunately, the case for the batteries is (located on the back) rather narrow. You have to fumble around a little the battery completely push in the pocket. As long as the material can withstand this hassle I can not be assessed currently.

Although the gloves be quite large you realize pretty soon that the batteries press on the back of the hand. This is certainly not pleasant in the long run.

Conclusion:
Good idea with potential. However, implementation is not yet fully developed and improvements would be desirable.
