Have to say yes. Just got SKU 2059504 and already had a bronze & copper one. The 510's are all adjustable but on my first (copper) it's always been loose and will slip back into the negative breaking the connection. Dental floss helped...a bit but I think is's time for Superglue. Even if I screw it up I've 2 working bases so I can switch chambers. All atomizers have their own characteristics but I fine the Tobh Atty to be one of the best in vapor quality & quantity.
