Caveat: the measurement results of both devices are identical, both units have identical storage capacities of the test results (60 Results for 2 people each are auto saved.), both devices acc. WHO recognized
Beurer BM58 benefits:
higher quality storage bag
stylistically beautiful device - already what makes her
Be able to evaluate PC mini-USB connector to measurement results on a PC
Test winner by Stiftung Warentest from 02/2010
Omron M400 advantages:
Oberarmmaschette makes a clear impression wertigeren and not threatened after some use give up the ghost.
Upper arm cuff for upper arm length 22-42 cm significantly larger area of use (Beurer 22-30cm or additional collar as accessory 30-42cm)
Connecting hose from the device to the cuff significantly longer than the Beurer BM58
simple push button operation - Touch control panel from innovators responded not always immediately (multiple printing when deleting the measurements necessary)
Result: have decided on the Omron M400, because I easier to acting unit prefer for necessary daily measurements although it clearly Biederer comes against the Beurer MB58.
