@b road blaster, I have received and tried the Bauway 510 bridgeless atomizer and found it brilliant to test eliquids. It is so cheap, uses so little liquid and produces a strong and clear taste. The first time it tasted a bit funny, but now it is working perfectly. It is so convenient, just a few drops and the full flavour is there. Once it starts to taste burnt, a few drops of the next liquid and the new flavour immediately takes over.
Thanks for a great tip.
