The Hollyland Screw Fitting for Mars 300 Pro is an official OEM expansion accessory designed to provide an ultra-secure, anti-twist mounting profile for the Mars 300 Pro transmitter and receiver units.

Standard single-screw cold shoe adapters often slip or pivot when your camera rig shifts quickly. This specialized mounting expansion plate screws directly into the chassis of the Mars 300 Pro to convert its base into a completely rigid mount that stays locked in orientation.

 

Core Design & Rigging Features

  • Dual-Screw Chassis Anchor: The plate features two integrated micro-screws that line up perfectly with the native alignment threads on the side or bottom of the Mars 300 Pro housing. By securing the transmitter at two points simultaneously, it completely stops the unit from twisting loose under camera movement.

  • Central Multi-Thread Integration: Once bolted onto the Mars 300 Pro chassis, the raised center portion provides a clean, reinforced $1/4"-20$ female threaded hole. This allows you to attach any standard articulating friction arm, monitor mount, or light stand stud natively.

  • Compact, Low-Profile Footprint: The plate is engineered with form-fitting chamfered edges that match the aesthetics of the Mars series. Its slim profile ensures that it doesn't add bulk or block access to the NP-F battery plate, HDMI ports, or the side OLED status display screen.

  • All-Metal Durability: Machined out of a single piece of high-strength alloy, this plate protects the composite casing of your wireless node from thread stripping caused by overtightening heavy-duty rigging accessories.

On-Set Installation Checklist: When mounting this plate to your Mars 300 Pro, tighten the two outer chassis screws evenly using a small flathead screwdriver or coin before screwing in your primary 1/4"-20 friction arm. Overtightening one side first can cause the plate to sit unevenly, which puts unnecessary stress on the wireless unit's internal threads.

Mostly fine replacement parts
Color: Omni S1 Pro 17P
I can't get either of the rolling mops to snap into place no matter what i do, might have to tack on something so they stay in place. The main brush was a fine fit, but the side brushes seems more flat than the stock ones and it makes some weird noise now, they did snap on though. Filter was fine though and I haven't tried a dust bag yet, still good value even if I can't get the mops to fit for me!

Exactly what I wanted
This robo-vac works great! Most of the well known products in this category are full of crap that you don't need, or is even spying on you. I'm sorry, but my appliances don't need WIFI, camera's, mapping features and an internet connection to send them to... who??? This unit has everything you need and nothing you don't. I bought it because my dog is shedding like crazy and leaving my floor looking like it needs a haircut. The Eufy has done a great job of picking up ALL of the dog hair, dirt and small particles, and has yet to become clogged. The floor it is cleaning is a linoleum floor that has a low pile rug and it cleans both very well. The Eufy runs for well over an hour and one of the best things about it.... it is VERY quiet. Emptying the dust bin is super easy, and cleaning the filters is very easy as well. The Eufy comes with extra side brushes and an extra roller. I have not had to change any of them yet, but maintenance and cleaning of these items has been made very easy as well. It comes with a well thought out cleaning tool that makes cleaning easy. It has a cutter on it, similar to an envelope opener, that gets under hair that wraps around the roller and and slices it off. This is a problem with ANY vacuum that has a roller, and this tool works very well for this. To be honest, I wasn't sure what to expect at the price point, but the Eufy works better than the older I-robot I had some time ago and is far easier to maintain. The very first time it ran it was learning the room and did not make it back to the dock, but every use since, it has always gotten back and docked. If you want a robot vac that you can start with a remote or program a schedule in, without WIFI, camera's, and yet another app to install on your phone, I highly recommend the Eufy... you won't be disappointed.
