It’s always true that unless you get face to face service with the HCP, REM is not going to be possible. A DIY person can’t afford to buy REM equipment just for personal use anyay. But if someone is a stickler for REM, one can always find a local HCP who would agree to do REM on a not-locally-bought HAs for a fee.
REM does give you a good starting point to know if the HAs’ performance is up to the target performance or not. But it’s not the end of the world if REM is not done. For starter, if REM verifies that the HAs perform close enough to target and little adjustment is needed, then IN THIS CASE, if you didn’t have REM, it’s not sorely missed IN HIND SIGHT since little adjustment is needed.
But if the HAs don’t perform close enough to target, without REM, it’s true that you don’t know right off hand. But that’s just an initial reference point to start out with (to be on the right foot). Even if you don’t have REM to tell you that your HAs don’t perform to target right up front, you still have your ears to tell you that, because you most likely sooner or later are not going to be happy with the performance of the HAs. So you’re going to work with your remote HCP, or in the case of a DIY person, you’re going to start tinkering with the Fine Tuning section, to make adjustments to get to a point where you’re happy with the result.
So no REM is not the end of the world. If the remote HCP is competent enough, they can overcome the lack of REM (not by choice but only because they subscribe to the remote sale model) and compensate for it in their adjustments for you. Same with a competent DIY person. Yeah, the journey to get there may be harder and longer without REM, but it’s not impossible. And in my personal opinion, it’s still a good compromise to forgo REM and compensate for it later so that you can save a lot of money by buying remotely.
