Hi guys and girls.
I use my Topside from January and my bottle need to be changed because the liquid
got some funny flavor and the bottle is already yellow where the squonk windows is.

I use the mod around 40-50 days till now and I did let the liquid in the bottle
when I did not use it for 2-3 days.

My liquid is DIY; usualy is 85 vg-15 pg or water, 5-6 % flavor.

What about your mod/bottle?
