question, who repairs the unit when it goes wrong, have they got a 2 year warrenty. The elctronics involved in modern spo2 units is so little that you are paying for the unit anyway by buying the probes.

Have they got assurance that after the 2 years the price isnt going to suddenly jump or can you shop around.

My old adage 'Nothings free in this world' were it comes to business that is.
