The Joyetech ESPION Silk with NotchCore Atomizer
I’d like to thank my friends at the Joyetech Company for sending me this device for the purpose of this review.
The ESPION Silk MOD is Extremely Lightweight due to its plastic and hypoallergenic Thermoplastic elastomers (TPE) rubber constructed case. It uses a 2800mAh built-in battery delivering 80W. The built in 2800mAh battery must be charged from a PC or wall charger. The MOD’s firmware is upgradeable.
The ESPION Silk has a 0.69 inch OLED display screen that is about 1/4" wide and maybe 2/3" long. The menus icons are small and cryptic, but are easy to figure out without the instruction book by just selecting each icon to see what they do.
After turning the device on with the normal 5 clicks of the fire button, pressing the fire button 3 times allows you to select the MOD’s operating mode. Wattage, Bypass, Temperature Ni, Ti, SS, TCR M1, M2 and M3 can be selected.
The directions on how to get into the menu was omitted from my instruction booklet, to enter the menu press and hold Fire and the + key.

The NotchCore atomizer is made of painted metal with a glass tank tube; it uses a sliding push-to-open top filling design. Slide the top cap to reveal the filling hole. The direction indicator arrow to slide the cap has now been darkened and is easy to see. There is some smooth knurling on the cap making it easy to grasp the tank to open it. The knurling is smooth but still noticeable. The tanks airflow has stops at full open, and full closed, and it can be dialed way down for a Mouth to Lung (MTL) vape. The tank comes in either Red or Black colors. It has an Industry standard “510” fitment drip tip.

NotchCoilTM atomizer heads are (almost) unlike anything you have seen. The tiny Stainless steel tube coil can be re-wicked, but it is easier to just buy new and change them. The new innovative coils come pre-wicked in a 5 pack and can be found for about $4.00, so they are much more affordable than standard sub-ohm coils. The suggested wattage is 20-30W and the suggested best wattage is just 25W, they are made of type 304 Stainless Steel (SS304). They have a resistance of about 0.45 ohm, I am able to operate the coils using the MODs TC SS316 operating mode, though it seems it is suggested not to in the instructions. The instruction manual states the Temp-SS316 mode is specifically designed for Stainless Steel type 316 only, but the NotchCoilTM coils are made of type 304 Stainless Steel (SS304). TCR set to 105, with 25W and 410F temperature worked well for me. The gold plated atomizer deck is specially designed for Joyetech NotchCoilTM mounted in a horizontal position, no other coil will fit. The airflow in the deck is right in the bottom, if it were slightly raised the coils would be easier to re-wick without causing leaking issues.

Because there is no removable battery there is a well-marked reset hole on the bottom of the mod if needed. The reset button is located in a hole near similar looking vent holes. To reset the device you would need a straightened paper clip, or similar small stiff wire.

I really like this idea; it’s a super lightweight MOD with all the features you find in all the larger Vw / TC MODs. It’s easy to grip, pocket friendly, and has really good flavor with absolutely no coil break-in necessary. What I dislike about the SILK with NOTCHCORE is its current list price, the least expensive kit I could find is about $53.20 and with its lightweight construction I just don’t think it should be priced that high, even with the low cost coils and technology built in to it. This device is on pre-order and the high price is subject to change even before its July release date, let’s hope the price settles to about $20-$25 then it will be a perfect transition kit for someone wanting to move up from their 1 button no display basic pen or pod starter kit to a device with the advanced functionality and performance of the more advanced regulated box Mods on the market.
Release date Early July, 2018
