I've had my Pulse 22 mm RDA for at least 6 months now. It was the first RDA I bought when I started squonking again in ernest. The Pulse 22 mm and its big brother the Pulse 24 mm were my 1st two RDA's they are still used even though I have a couple other RDA's that cost considerably more and are great RDA's in their own right. Still the Pulse 22 mm is one of my favorite RDA's, its a single coil postless deck which is extremely simple to build on. Just clip the ends of your coil to the proper height so they won't interfere with the top cap or anything else under the hood. Once trimmed to your liking drop them in secure the slotted screws on each end, wick and drip, it's just that simple. You can use this as a regular dripper RDA, or like myself use it as a squonker RDA which is my preferred mode. I did however use this as a regular RDA as I was waiting for my first new squonk mod since my first Kanger Dripbox and the Dripbox 160, both of which I no longer have as I have much better gear now that I have gone to the squonk side as this is about 99.5% of my vaping now. What I like about it is the size and it is a nice little single coil RDA which in my opinion when using a nice micro coil. I prefer something around 0.18 - 0.24 ohms with a single coils build the flavor and vapor production with this RDA is spectacular! Get one....try one, use it as a regular RDA or as a squonker RDA, you too will be surprised at just how well this little guy performs!
