Love them love them. But if you buying for you supbox pro you'll have a bit of difficulty using them. As even though its sxk and most everything else is compatible with billetbox and there boro and other rba and tanks are likely to he compatible but these are not. They are for the billetboxs. And them only. I did happen to find a way to get to use them with my supbox pro. I flipped the top tension plate and had the screw it up from the bottom up and counter clockwise at that. From the top you can't get it threaded anywhere near enough to make the metal on metal contact needed for the boro tanks to work when tensioned all the way down. After getting it screwed in the slightest bit from the bottom I pop onto the boro and then to the 510 contact and then hold the plate down and finally the battery tension screw down to hold it all flush and everything works. Its obviously not what I'd like as In risking ruining the small sxk threading with larger metric style the threading on the mission drip tip. And the will not be able to use the standard threading that comes with the supbox pro. But I like them it looks nice. The airflow is great and can be from wide open to the tight mtl style. Very versatile. Looks great. And yeah made for the billetbox not sxk supbox pro. But I got it to work. Not recommended. And got lucky. Might have to look into re threading that tiny part to the real small supbox is supposed to have or might have to buy a billetbox instead.
