Hi,
Ive being using my ruyan e cigar for about 6-7 weeks now and am very impressed, the ruyan liquid is spot on and strong.
Im on my second atomizer now, the first one lasted about a month of constant all day everyday use (it still works but is weaker than my new one).
wayne at heavens gifts told me how to clean it , below is exactly what he said -
1. Put the tube into clear water (without any risk for the atomizer!) (no detergent! nothing other!!!).
The best solution is to let the tube under flowing clear water by the two holes some seconds.
2. After the cleaning, you have to dry it blowing and blowing again into the two holes of the tube to eliminate all the water, you can also securely use a hair drier to activate the drying and to be sure it's well dry.
3. Then you have to put a new full filled cartridge in the e-cigar, wait 2 hour or more waiting the liquid arrives to the atomizing chamber and insert the full charged battery. Or you can squeeze liquid from a cartridge and drop it into the e-cigar.
4. After 2-10 slow puffs, if a high density smoke appears as the first day, then all is Ok.
Wayne is very helpful and will replace faulty items under warranty if you send the faulty item back. postage for a fualty atomizer to china cost me £1.67 . He sent the replacement with my next order of spare carts.
you wont regret buying one

. Just waiting on one of his penstyles to arrive , hopefully will be here today.
