Original Review:
Having our friends, our old equipment donated (They were all enthusiastic), we have two new kekauft. Thus began the report problems. The device came with pre-mounted batteries and worked only sporadically. Time you did not go, then. So we complained to the manufacturer Riemser. We have you sent in and will be returned after 2.5 weeks. "Concise statement of the manufacturer: The equipment is in order, we have the batteries been inserted incorrectly." (But they were indeed the factory pre-assembled on delivery) Now after almost 2 years we still get angry about it. Time do not go, then.
Last batteries that had to replace me, I have measured it and who still had fewer than 1.47 volts and the device still does not work anymore with it. The new batteries have just 0.09 volts more (battery = 1.56 volts). Now the device is again a few weeks with regular interruptions run until we have to replace the batteries. We use the device between the battery exchange more than 15-20 times.
My conclusion is:
The new generation of devices is not really reliable and needs in Gegenbsatz predecessor a lot more power. The Bite aways we will no longer be replaced with new ones. A recommendation can not really speak well.
To this end, there is only one star!
