Bambu Lab AMS Lite

Works quite well, haven't had any issues yet with spools. Very minimal assembly required. Very good for shorter prints that require multi filaments, but if you're doing a considerably longer print (the filament swapping alone can add up to a lot of time depending on the print) you'll need to take into consideration the dryness of the filament. You'll likely want to store your needed filaments in a silica dry box or filadryer (Sunlu S4) and feed from there into the AMS lite.
