I second mindshatter's post. I did not buy the Version 1.0 L-Rider Vtube---lack of resistance checking and the underperforming 2.5 amp limit were deal-breakers for me---but I do own both a Vector Variable Volt from VaporBeast and a Varitube X from iVape. Except for the rebranded names, they are identical V1.5t units from Young June.
While I can't comment on how the V1.5t compares to the L-Rider V1.0, I do have 17 other VV mods, and both of mine perform as well as any of VV I own.
Yeah, they do have the "stealth mode low power" glitch if I press the power button an extra sixth time after the 5-click power off sequence, but that doesn't bother me much since I never take either one out of the house. What the V1.5t apparently doesn't have, however, is the shorted-out chip meltdown problem that at least one unit of the previous version V1.5 (without the "t") had, where the aluminum casing of the chip assembly shorted out one of the three chips and caused the unit to fire by itself and not stop firing, plus melting the display and ruining the
device). Both VaporBeast and iVape told me that their distributor rep had assured them that Young June fixed that serious flaw before making the V1.5t. While something that a rep told a vendor provides no iron-clad guarantee that Young June did indeed remedy that potentially dangerous design flaw, I've not heard or read of any 1.5t units suffering the failure.
Supposedly, Andrew at CCV (it was his personal V1.5 that melted down) is getting the chrome V2.0 from Young June---with the amp limit increased from 3 to 4 amps---to offer as a replacement to customers who bought a V1.5 from CCV, but those haven't arrived yet, so time will tell.
