Great breakdown of the STS3250’s real-world performance — those repeatability and torque numbers are especially impressive for this class of servo. It’s always helpful seeing tested data instead of just spec sheets. That said, whenever I’m buying hardware like this, I also double-check retailer policies in case something doesn’t match expectations, like the Best Buy return policy outlined here: https://best-buy.pissedconsumer.com/return-policy.html . Solid reviews plus clear return options make experimenting with components a lot less stressful.
