I am reaching out regarding a issues we've encountered with a particular fingertip pulse oximeter model. It seems that the battery compartment design is incompatible with standard AAA batteries, which poses a challenge for our users. This might affect overall device performance and user experience, so we would like to explore potential solutions. Could you provide any insights on whether there's a revised version of this model that addresses this compartment issue? Additionally, any recommendations for alternatives that maintain similar functionality would also be appreciated. Looking forward to your feedback on this matter. Thank you!
