I was part of this recall, bought the 552 back during the pandemic. So I only qualified for a $50 voucher towards a new model, which happened to release at the same time of this recall announcement. Looking further into the recall, it only affecting something like 2% of the dumbbells sold.

I’ll take my chances with these dumbbells I’ve been using for the past 5 years rather than them trying to upsell me on the new model.

Have you checked if your local area is on another channel besides the default LongFast?

For my area, most of Northern Georgia/Atlanta is on MediumFast and there’s a good bit of nodes and participation on that.
