My lunar was second hand / ex display from Hasbean when i got it. ive had it about maybe 4 hears.
It survived a bombing attempt by my wife launching a heavy weight at it. I filed down the offending lump missing from it. It’s there just to remind her. I never tried to paint it back to back.
Had a swollen battery maybe 18 months ago, replaced from amazon.
I must admit i actually never tried Acaia customer service.
Test weight still reads 100.00g
Had it when i had the sage DB, synchronika for timing and weighing.
Since moving on to the evo its just required for weighing beans and dialling in. Overkill now, yes, but wont replace until it dies.
It is very quick to respond and 100 percent repeatable. It gets wet regularly.

I sold the leveller to stop her having a second attempt it was useless anyway!
