I love the OWC Thunderbolt Dock for my M1Pro MBP but I’ve only had it less than a week. It had a hiccup the first day but I think that was a fluke (described here: OWC Thunderbolt 4 Dock and MBP Power Settings).
As others have said, make sure it works with the M1 Macs. Think about the ports you want/need. You’ll want to be sure the dock supports the monitors that you have (or maybe even a future monitor). And you may need adapters to connect to your monitors.
I chose the OWC dock because it has 3 Thunderbolt 4 ports in the back. The one on the front connects to the Mac. I only use one external monitor and since I only want one TB cable connected to my Mac, I use one of the TB4 ports on the back to connect to my monitor. Additionally, some USB ports are for data only (I am not sure if this means that they only can’t charge a device, so I’ll defer to others for info on this).
@PlayerToBeNamedLater mentioned the use of longer cables. I currently use the OWC-supplied TB4 cable to connect my Mac to the dock. If you need a longer cable you need one that will provide the necessary speed and power, or else these things will suffer. I purchased an expensive 79" OWC TB4 cable but haven’t tested it yet. I need the longer cable because the dock will reside under my desk and I need the extra length to accommodate when my standing desk is at full height.
I’m no expert and not necessarily recommending the OWC dock for you but just giving you some insight into the thought processes I used before I purchased my dock. Read the specs carefully before you make your decision.
