“Incredible goodwill of the supplier HMM Diagnostics
I have used the device for 1 year as intended and wanted to replace the battery, which I failed; I messed up the opening notch on the lid.
On my cover letter, I was given the opportunity to send in the sensor, have it repaired and even play new software; Return postage was not required.
I wish that as many potential buyers appreciate such a goodwill and prefer to order from this supplier !!!
Many thanks to HMM Diagnostics GmbH “
