Larger Saramonic (analog) UWMic9 kit has locking connectors. I'm very happy with it, I use it in dual-channel with the (optional) XLR out cable. Excellent performance for the money, it's actually made on an older Sony production line (which Saramonic bought), so externally it looks like a Sony copy.
I think the main use case for this digital product line is with the TX clipped to the shirt and using the internal mic, but they shouldn't claim it's "Pro" gear. I was contemplating the (non-"pro") Blink500 last year, before corona-san.
Chinese issue with connectors (and their quality!) and wires is constant.
Their lav mikes wires quality is mostly horrific.
non-locking connector on TX, fail.
