Uniq/Young June are now offering Vtubes that compete with the L-Rider/Knight/J-Lin Lavatubes.
Young June's most current offering is called
Version 1.5t, and goes by various rebranded names according to vendor: Vector Variable Volt from
vaporbeast, Varitube X by
iVape, plus another from
VaporAlley called (incorrectly) V2.0 Tube. All these are identical. They're offered in black or silver, have a roughly 3-amp limit, sleeker all-metal end caps with a flush 510 top connector, plus atty/carto resistance checking with a single click of the power button (no menu system that requires multiple click-and-wait morse code). They also have a glitch in that they don't power-down correctly (they can go into "zombie-low-voltage-mode" and will still fire, even though they seem to be turned off). You'll have to search the
threads to read about that and decide if it's an acceptable flaw for you.
The Version 1.5t uses an innovative implementation of PWM (pulse-width modulation) that seems to provide considerably more power and a better
vape across the entire range of voltage. That's an opinion, of course, but it's held by many people (including me), and I haven't seen any L-Rider V1.0 owners dispute it.
Current models of
L-Rider Vtubes are called
Version 1.0 (the original "Lavatube" in black or silver, and on rare occasions in red, with the nubby plastic-coated end caps) and
Version 2.0, called the "Lambo" (in stainless steel or chrome, with all-metal caps and a spiffy eGo-style top connector that has a spring-loaded positive center pin). Unfortunately, both L-Rider versions are 2.5-amp limited and use that mystery voltage drop method of staying under the current limit that many people didn't love. Neither version offers resistance checking.
L-Rider' Version 3.0 should be available soon, which will raise the amp limit and add resistance checking.
By the way, all L-Rider Vtubes have a red power button, whereas all Young June Vtubes have a power button that matches the body color. That's an easy way to tell them apart.
