KTS-GGTS, aka China GG, aka CCTS...
Received my vape-mail today, yayyyy!

Picked-up from the mailbox. Just a light, small envelope 7x5 size.
Can feel the bubble wrap inside. Neat job by
Hoosier Vapes.
UNBOXING and FIRST IMPRESSIONs

Ordered the China GG and a Steel Drip Tip. Each is individually bubble wrapped.
Has the Invoice and two Business Cards inside.

Opened each bubble wrap. The contents of each come in their clear plastic pack too.

Wow
! Nice and Shiny. The first impression is too good... awesome - feels classy.

Back-to-Back

Individual parts/components. Quite well made. Strong & sturdy.
The Centre Tube (telescoping section) is the lightest, feels like a sheet-metal work.
Rest of the tubes (top & bottom) r pretty strong. All BRASS.
The 510 head section and the bottom cap r very heavy.
Unlike reports elsewhere, the bottom spring is NOT SOLDERED, rather "flush-fit" into the post.

Here's both the heads separately.
Note the firing switch. The end protruding inside has a nice wedge post. This one is strong.
There's no way this thing could ever miss the post and misfire.
Also note that the bottom tube has a built-in 'stopper ring' under the Battery,
And the firing pin is above it, beyond the threading for the end-cap.

Top view of the sections.
Note the "airway slits" all around the top cap.
There r eight (8) of them, 4 in the 510 connector and another 4 on the periphery wall.
This device can never give out a tight draw, under any load (juice delivery system).

Thought of showing the spring loaded section once again.
Note that the spring actually goes "inside" the bottom post. It's not "over" it.
And the spring is all BRASS, plus very tight. It's not made of a std thin-wire.

Pitted against my
Sigelei #8 (in 18350 mode). The CCTS has an 18650 Panny inside.
Note the difference in their firing switches. The CCTS one is more stout.

Took a closer view of the switches.
The CCTS switch indeed has a stronger, sturdier and robust design.
The knurled locking-ring is wider too. Gives added assurance on its durability for sure.
CONCLUSION
Overall, the KTS-GGTS seem very nice. Gives me good feelings. The construction is superb. Some nice machining there. I specifically chose the "dual-tone" model... and I'm thrilled at it's gorgeousness. The gold / chrome combination indeed is stupefyingly beautiful. It has some quality thread-work gone into it. Sliding the telescopic section, as well as fitting the top & bottom caps, is like slicing cheese with a butter knife... smooth. I've vaped the device (with an LR
Boge F-16 only) for over 3-hrs now...
and it has been quite satisfying. Needless to say, I'm impressed. This is a good-looking, powerful and efficient Mod.
A head turner at that!
