We are testing batch 4 for a whole day now. Personally I've been sucking nonstop with usb, with batteries, with auto switch, with manual switch... it works flawless! Don't ask me how my head feels though
I will continue suffering for the rest of the weekend, just as 2 other colleagues. I will let you know if I approve this batch or not, by Sunday.
What has changed in batch 4:
New screw thread to avoid short circuit (possible problem for some non working switches, usb cables of previous batches). This means: yes you can use batch 4 switches with previous batches batteries and usb cables, but it doesn't screw in perfect and leaves a 1mm hole between the two parts. I suggest you keep batch per batch parts.
Auto switch: when you screw it in, the LED blinks 3 times, this means you have made contact and you're good to go.
Auto switch: you puff like crazy, non stop - result: the switch blinks about 40 times, notifying you that you are puffing in a very unhealthy way and therefore the system shuts down for 20 seconds! After 20 seconds you can puff again.
Auto switch: the led light is more visible now (bigger hole), now you can even use it as a laser pointer if you wish.
Manual switch: no change in usage - you push the switch = full power. No safety program, just ON/OFF switch. You are responsible. If you push for 30 seconds for example, there's a big chance you will overheat the atomizer and cause the death of your atomizer, so please be reasonable when pushing that button! Push for 8 seconds maximum if you can inhale that long!
Knowing that some of you WILL kill it, we have lowered the prices of the extra's for the KISSBOX, an atomizer costs 26.5 instead of 47 USD now!
USB cable: connect and let the battery inside the USB battery compartment charge for an hour before using (ok I just let it charge for 10 minutes and puffed away, but I need to speed things up as you all now!).
Atomizer: no need to dry smoke! Too much liquid inside? Just blow it out the atomizer, put in a new cartridge and you're ok.
Feeling in your lungs, in your throat? First of all this something personal, I just did a test with a light smoker and she coughed (ruyan nr4) after just one puff! Need more feeling in your lungs? Suck/Inhale 5 to 7 times fast and strongly into your lungs. I need to warn you, this is for heavy smokers only!
Please use this device, and any other e-cigarette for that matter, as you would smoke a normal cigarette. Don't be afraid of not getting the kick, be relaxed when you inhale and inhale deeply, don't rush things.
just my two cents, Ludo
