Alternate remotes with 6 or 8 buttons

I have the 4 button remote communicating, but I was thinking 8 buttons would be ideal, adding Auto/Standby and Tack Port/Starboard.

Looking on AliExpress there are a few candidates, and I though I'd see if anyone has feedback before I order:

433 Mhz Universal Wireless Remote Control Switch 6/8/10button RF Transmitter Electronic Lock Control Diy smart home
This one is inexpensive, but doesn't look well sealed. I can't tell if it's programmable, so I might need to change the code to match the remote's pre-programmed codes.
Even cheaper, fixed codes: Universal RF 433MHz Wireless Learning Code Digital Remote Control Transmitter for Switch 1/2/3/4/6/8/10 Button 2262/EV1527

AK-G06T Factory Supply High Grade Remote Control 315/433MHZ Wireless Industrial Crane Truck Remote Controller 4/6 Button Keys
This one only come in 6 buttons, but looks more rugged and is a learning remote. Can't tell if it is sealed either.

Q400 LCC High quality industrial remote control switches AC220V 380V 110V DC 12V 24V 36V Lifting crane control
This looks very rugged, and is 433 MHz, but who knows what the transmission protocol is.
and another: A600 Electric Winch Control Switch F21 E1b Industrial Wireless Remote Control Eot Crane Remote Control 6 Channels

The A600 and Q400 won't work, because they use GFSK (Gaussian frequency-shift keying) modulation rather than the RSB6's ASK (Amplitude Shift Keying). A different receiver would need to be used. Perhaps the RFM69HCW.

I have ordered the 433MHZ version this 8 button remote for testing. It says "IC:SC/Pt/2260/2262/2264/ EV1527" which I think should work with the RXB6 receiver.
