Hydrow just announced a new smart rowing machine, with no subscription required

Hydrow, a company that makes smart rowing machines, just announced the Core, a new model that eschews monthly subscription fees. The Hydrow Core Rower features the “same award-winning design” as the original Pro Rower, which we said was positioning itself to be “the Peloton of smart rowing machines.”

Obviously, the hook here is that the Core is a one-and-done purchase with no recurring subscription costs. It still comes with an attached display, which lets users “row through stunning destinations.” All told, this machine offers access to 30 self-paced rows through these exotic locales.

Hydrow

The Core Rower supports unlimited users, which is nice, but there is one major caveat. There’s no subscription, so there’s no access to instructor-led workouts, badges, milestones and other premium features. However, customers can add a membership later for all of that stuff. Hydrow charges $44 per month for a subscription. It could be useful to try it out for a month to see if all of those additional bells and whistles are worth it.

The Hydrow Core Rower is available right now and costs $1,995. This is the exact same price as the flagship Pro Rower. The company also recently released a trimmed down version called the Hydrow Wave. This one is smaller and cheaper, clocking in at around $1,700.

Five Reasons Why Customers Leave

I was recently hired as a keynote speaker to talk to a group of financial advisors about client service. One of the topics of the meeting was a discussion about why a client would leave. The most obvious reason might be that the financial advisor gave bad advice, and the client lost money. But let’s assume the advisor is smart, the advice is sound, and the return on investment meets expectations. Even with all of that, why would a client leave?
