Great idea, solid exterior but incredibly quiet

To my review below, I would like now, after a few months and already-exchanged devices more, unfortunately negative criticisms list:
We have found that once there are sources of interference (electrical loads, other PMR on other frequencies, ...), the devices runterregeln the reception sensitivity or simply have a so bad squelch that just comes through anything. Here the examiner has only a reboot. That may be OK for the amateur radio operator or fun kids games, if you have but to rely on the readiness to receive, this is an absolute "no go" and thus a KO criterion. Furthermore 600mAh rechargeable batteries and a battery level indicator, the "full battery" until the device switches between the range of display from an empty battery in less than 30 minutes are going through anything but the price range reasonable.

I use radios for easy communication while verification activities on wind turbines. Here is radioed from one plant to another or from top to bottom.
To date simple TLKR T6 Motorola were used because they were small and handy. Now it should be a little more robust, but still handy. Due to the numerous positive reviews I have accessed this machine. Compared to approve T6 immediately falls on the more massive and thus sound more voluminous housing. The Loudspeaker comes across clean and understandable. What becomes immediately apparent is the relatively low volume. As an example: the put in a normal car, a unit in the footwell, the other at the mouth is understood at a speed of 100 not another word. Or another example: radioed in the second row in the T5 Multivan from the passenger seat, going at 100km / h and nothing more, if you do not, the receiving device adheres to your ear.
These examples are intended to roughly show just how quiet the T80 are extremes. The cheap T6 are indeed plärriger but much louder in the described noise. For our commitment to wind power installations where quite times a hydraulic pump or a fan motor running, they are useless, since one is not aware the radio partner or does not understand.
Another disadvantage is the attached belt clip. These dissolve, thanks to thin plastic, even at very low rotational or pressure. Again, the cheap models are much more stable and secure sitting.
Finally, I have tested the models on a weekend time on the bike. The accompanying headsets fit well, are comfortable but again much too quiet. There are also on the receiving device at the start and end a transmission for the ear very unpleasant crack. Last point of criticism is the 5-step einstelbare, voice activated transmission control: at level 1 suffice slightest breath sounds and wind noise to activate, at Level 2, the device jumps, if you count out loud, at 4.5 or 6 to, at level 3 you have almost scream and you will be minimal quieter, stops the transmission (CRACK !!!).
I would recommend the device against this background to this application if any.
