Weaknesses:
- Processor a little slow; Select the functions expected to go quite a bit faster; which of course you do not normally permanently in the "rumwühlt"
- The handset could still do with a volume level, for normal hearing but without any problems; who no longer has the best hearing must make cuts here
- Differences in quality of the supplied battery; possibly need here after a year use to be replaced (2x standard Micro AAA battery, but this should be to get over)
Conclusion: The new Sinus A405 obtained quite good device that can keep up with the Gigaset relaxed or Panasonic devices in this price range, possibly even a little superior.
In any case, the new series 205/405/605 are a good buy recommendation.
