SS3 Key Fob Life (It is all over the place)

I upgraded to SS3 in early 2018 (I previously owned SS2). I read concerns about the Key Fobs not having a replaceable battery (as SS2 did). All replies were, "Don't worry, if the Fob fails, we'll send you a new one free of charge." (That is not verbatim but was the standard response and narrative at the time so many were voicing their concerns). I purchased two, and one (rarely utilized) failed precisely four years later. The other (used often) failed five months after that. SimpliSafe replaced both with new products. Fast forward to last week, and the often-utilized Fob died – just one year and five months after replacement. No one ever dropped it, and it was well cared for. Today, I received the replacement Key Fob and was surprised to find it refurbished. I never buy refurbished products and am rather unhappy as no one told me the replacement would not be new.

Additionally, I could understand SimpliSafe's initial claim that the Key Fobs last "up to 5 years, depending on usage." The system (SS3) was new, and thus there was no actual customer usage data. Now, that should be more accurate. If the rarely used Fob lasts four years, and the other utilized almost daily lasts five months longer, that shows a high variable for inconsistent battery life. Add to that the new (condition) replacement that only lasted one year and five months, which signifies a problem with the product's batteries.

I understand many no longer use the Key Fobs, but if SimpliSafe sells them, there is a market/customer for them (I am one of them). I am posting this to hopefully trigger some follow-up testing now that SS3 has been available for 6+ years. You now have solid data (as opposed to hypothesis) to stand by or reword/change the life expectancy of specific products offered. For instance, how many replacements does SimpliSafe send out, and how many customers return dead Fobs? What percentage is that, and how many years on average are they lasting? Is it to the point where there are no more new products to replace mine with? I know that happened (understandably) with SS2, but I highly doubt that is the situation with the new SimpliSafe system (unless a new system is coming and production is ramping down).

As someone who never purchases refurbished products for a reason, I do not know how long the replacement will last. More importantly, though, solid data is now available. In my personal experience, the Fobs' battery life expectancy is vast and much broader in range (i.e., shorter) than the company lists for this specific component.

P.S. When replacing new components with a refurbished product, please state that clearly to the customer in the future. I was quite displeased to see it was.

Thank you.
