Round satisfactory product

Have brought me the part, because I was looking for a Bluetooth receiver which works even while you are charging. Reason: If the car is connected to the AUX input of the radio operated. The receiver is next attached with Velcro on the dashboard. Works perfectly.
Pairing has for the first time to run at all, but was then never needed (which is why I have the procedure already forgotten).
Mobile Bluetooth function on, RAIKKO at => connection is established automatically, even if the cell phone will disappear from the reception area and later come back (assuming the power saving function has the RAIKKO not sent off to sleep what it minutes after 5. Without makes Pairingpartner Receptionist).
Occasionally, the transmission does not work, but I laste to the K850i, as it also happens with the same type BT3030 Bluetooth receiver (Jabra). Opposite this is missing the elegant keyboard light and there are slight gaps in the sound (the tone controls on the car radio compensates for this), otherwise the part fully OK.
Especially just because it can be used during charging. Unfortunately, an existing connection will be disconnected when you plug the charger plug (mini-USB -> I was wrong, as I now know only looks almost like mini-USB.), Then has to be rebuilt, but it works ,

But one thing displeases me: The time for the switching on or off!
The button must be about 4-5 sec to turn already. are pressed. But completely nonsensical is the power off for the button Felt 10 sec. must be pressed: I always count to 10 in front of me before the confirmation tone. This one benötig but also because to pressing only redial the last number triggers (from approx. 3 seconds holding the button).
Also visual feedback is not given since cleverly the (only) display is in exactly this button, which you have to press and thus is fully covered (with my sausage fingers). Otherwise could not wait man, up to the usual blue operation LED flashes red briefly to to signal the turn.

Quite so bad but that is again not because you can leave it turned on.
As mentioned above, the part turns off after about 5 minutes even on its own.

Conclusion:
It would more, but for me the use during charging was more important than many other things, and the sound and function go fully in order.
Uptime I've never mitgestoppt, the manufacturer's instructions seem at least not implausible. In my case, I go then anyway to rechargeable specification.
Even the Empfangsbeich in usual operation is not quite as great as the BT3030, but it must also not be at my constellation. Whether mobile phone holder (20 cm next to the part) or shirt pocket, or (at worst) pocket on the rear seat: connection quality always OK. The promised 10 m manages but only with the free "view".

Supplements 9.9.2010:
I see by chance, the design has changed in the meantime (now looks almost exactly like the Jabra BT3030). I have a device rated that as a small clip looks with thicker front. To what extent the Techik has changed course also evades my knowledge.
Meanwhile, there are also more secure knowledge about the battery life before: 6 hours are definitely not (more?), More so to the 4 hours but may be due to aging, batteries are just wearing parts...
