@Wayneo has covered it!
So with an empty Boro Tank you can get bridges that allow for the most common stock coils such as Nautilus, EUC etc and now bridges for the latest coils such as the Voopoo PnP coils, you also get a ton of RBA bridges both high end and cloned.
The all in one Boro tanks have an RBA built in and many are a version of a popular RTA like the ether and can be both high end like Atmizoo did a version of the Vapeshell called the Vapesnail or can be more mainstream so BP Mods are releasing a Pioneer which is a Bridge version of their popular RTA.
You can also as well as BB or BB style devices get spin off devices and tanks such as the Supbox which allows a Boro to be used on a device with a more traditional looking form factor which can also use standard atomisers:
Then there is the Abyss which has a more traditional cylindrical tank that allows BB bridges to be used:
Finally there is a cylindrical tank with a standard 510 so can fit on any standard device but allows the accommodation of a bridge called the tell which has also been cloned!
