I usually try eliquid out by dripping on a Joye 306 or 510 atty,they will fit 510 and Ego threaded devices,are very tolerant of flavor changes and you don't ruin a tank or carto with nasty liquid.A lot of us just drip around the house for better flavor and use tanks or carto's out and about for ease of use.
Just one? EC Blend's Chocolate Malt gets vaped at a slightly higher rate than anything else I have on hand. Light on TH, but for a dessert vape, that can be a good thing. At 50/50 PG/VG, which is EC Blends starting point mix, vapor production is excellent, and it tastes great (to me).
USPS doesn't have the greatest tracking but it usually means that the person you are buying from has created the shipping labels but the mail piece hasn't actually left the warehouse yet.
Depending on how long this notice has been active, say more than 48 hours, it could be that the items have already left the warehouse but USPS hasn't updated yet. Most likely this will update once everything reaches customs in the United States.
It's just part of ordering from China, your always sort of on edge
