How to verify date of sale on 2.1 SA Doser

[Reefahholic]

The sale date would be based on the date written on the sales receipt. For warranty purposes, if one is not available, then we would go by the build date of the device. It looks like this one was made in 2016.

Thx Vinny. You’re always a huge help. The reason I was asking is because I’m picking up a 2.1 SA tonight and the guy was saying the plastic blue caps were replaced, because they were defective. I have had 3 2.1 SA doser’s and have never experienced this beyond normal wear and tear.

This was his quote below:
“The circular ring inside the cap that hold the rollers was either a tiny bit too small or shallow and the rollers were grinding the wall until it cracks.”

I googled it and it did appear there were a few minor issues with the old caps/rollers. He replaced his with all new caps- “Version 2” as he put it. I have not seen this new version yet so I can’t verify if that is true. I’m sure you already know, but he was saying it affected models between 2017-2018.

I’m hoping that it will be good to go now. Please let me know if this issue has been resolved or what I need to buy should I have any issues.? Thx for the reply!
