The Spica pro is probably my favourite mtl tank ever, it vapes like a dream and aesthetically, for me, it's near on perfect. The only downside is the glass can be a little tricky to remove to clean as it's quite snug, I broke my original glass but managed to save the day by using the glass from a Kanger subtank and a couple of wraps of dental floss under the 'o' rings and jobs a good 'un! It's a tank that ticks all my boxes, but my days of duplicating too many tanks are well behind me, it can get out of hand fast!Thank goodness, you've saved me from myself... I DO NOT NEED A THIRD.
