No regrets
i think it is a necessity if you have an oximeter, to have the  carrying case for it.  however, every time i took out my oximeter, it was on, draining the battery.  and then i figured out to keep the oximeter sideways!  yeah, that works!  so do not hesitate to purchase one for your oximeter, just store the oximeter on it's side in the case!
