Going to start with the KFL with the Svoe Mesto logo SKU:
13202. This sucker is heavy, the seams are invisible. Threading is very clean. This does not have an adjustable air port and the juice channels are a bit deeper and wider than the other KFL's I've gotten from FC. Juice is put in through a fill port on the underside of base, with a Phillips screw with o-ring to seal, kinda like the Real KFL which had the leaking fill port!

The threading there is also really clean.
*NOTE: This unit does NOT come with tools, additional wire/wick/o-rings/screws, or an extra metal center ring to exchange with the poly ring.* The logo is actually a brass/gold color with black print underneath. "Made in Germany", "Designed in Russia" and the Svoe Mesto logo on the bottom of base. Comes in a plain black box, similar to a spark plug box, with "Made in China" on it, with the KFL sealed in clear cellophane. 84 grams total weight. Very clean build and look. Brushed silver finish. All 3 are pretty much exact, I can't find any differences. O-rings are pretty stout. Adjustable pin on the base. Very good buy for $15.32 each, currently listed at $15.63 (I got them for less doing the "bulk buy")

Squape SKU:
13164. Another heavy topper, 90 grams (urgh, so much for a "Universal" measuring system! Give it to me in ounces! Will metric ever be the norm here?) The drip tip DOES come off, just forgot to take it off in the pics. The stack/chimney DOES have a different coating/finish, as does the coil platform. Coil screws can be tightened/un-tightened by finger or flat head screw driver. Noticed the same "tool mark" on both coil bases, no biggie. Threading throughout is sweet! Air hole is just above the 510 threading under the base. Will have to see if it needs to be enlarged. No fill port, juice is put between the stack/chimney and inner wall of the exterior housing while upside down and base is screwed on. Juice channels are clean, deep and wide. Adjustable pin on the base.

Comes in a "Taifun" black box, stamped "Made in Germany". Bottom of base has a serial #. Squape comes with extra o-rings, wire and wick, Allen wrench, but no extra coil screws.

That shouldn't be a problem because they do screw down into the base more deeply than some other RBA's. Currently sold out, but got these 2 in the "Group Buy" for $18.95, site has them listed now at $21.36. Polished silver on the outside with grooves in the center portion and knurling on the outside of base to grip onto when putting it together or taking apart. +1 for that great idea!

This is a pretty easy set up. Just 4 main pieces, the base, the stack/chimney, exterior housing, and drip tip, no multiple threaded stacking exterior rings to put together like the KFL's. Clear "windows" are poly, but not an issue for me, I have yet to indulge in a juice that cracks or melts/eats non-glass parts.
So now all this stuff is going to get cleaned and I'll report on their performance. If you can coil KFL's, you can coil Squapes, and vise versa. The Squape's coil screws are really nice, a lot better than those dinky little screws I always fear I'm going to loose or strip.
