Looks like I am likely about 3-4 days away from shipping most outstanding Solo orders, and maybe a total of 14 days from shipping all of them.
If you purchased a Solo and would like me to add Metr to your solo you can buy the add on here
For now the process will be that this will need to be purchased with Solo at the time of purchase, I have to load custom FW for the BT module to unlock this feature before I mail it, it will come with a pairing code. the code will be random unless you have one you prefer to use, you can email me your personalized code when you purchase the add on and I will set it to that 6 digit code.
Side note since a solo dual is 2 singles mounted to the same heatsink, basically one of them will have metr, the other will have a regular BT module. You can use both or either for whatever. And if for some reason you want both to have metr purchase 2 metr add one and I will send 2 separate pairing codes
