Good product, but phenomenal customer support
I've had the Sonnet Echo 21 Thunderbolt 5 dock for over a year. My setup is pretty demanding, 64GB M4 MacBook Pro Max, two external monitors, and I regularly do LLM fine-tuning that keeps the machine pegged for hours. Under that kind of sustained load, the dock would occasionally cut out. I reached out to support over a year after buying it, honestly not expecting much. They had me ship the unit in, their team looked at it, reproduced the issue, and gave me a full refund - no hassle. The dock probably isn't the right fit for anyone pushing extreme, prolonged power draw but that's a pretty specific edge case. For most people it'll be rock solid. And honestly, the support experience alone would make me buy from Sonnet again. A no-questions refund on a year-old product isn't something you see often.
