I'm going to put a slightly different spin on the clamp and USB issue. This was mentioned to Tech Support, by the way, while discussing an unrelated Einstein issue.
The literature that was available before and after the VML introduction gave the impression that the clamp would securely attach the VML to a lightstand. Absent anything to the contrary, it was anticipated that the VML would always stay put, even if the lightstand were thrown over a shoulder. As it turns out, this is an iffy proposition that would very likely lead to a broken VML. In addition, the literature did not specify a max diameter of 1.25", nor did it state that the bottom of the VML had to be resting on a joint, knob or knuckle. Reality eventually fell short of expectations.
Similarly, there are issues with the USB port. Buyers expected to have an additional way to charge any USB device that drew less than 0.5A. However, it's already been reported that some devices (i.e. iPhone) that draw 0.5A or less will not charge. I'm not aware that this discrepancy has been explained.
Personally, the clamp and USB port on a VML is sort of like a remote starter on a car; very nice to have, but totally irrelevant to its primary purpose. Even so, owners would do more than simply shrug their shoulders if they got home and discovered that the remote only worked while buckled in the seat.
One way to handle this is to ignore it and do nothing. However, a better option might be to manage expectations by modifying (1) the VML description on the PCB website(s) and (2) the VML Quick Start Guide. Just publish the restrictions in both of those locations, and life goes on.
It was not stated that "that the VML would always stay put, even if the lightstand were thrown over a shoulder."
Surely, every light stand has a tube less than 1 1/4" somewhere above the bottom section.
Many users have reported that just putting a piece of thin rubber on the inside of the clamp will hold it securely. Also, replacing the spring with a short piece of 1/4" ID tubing will allow tighter clamping. Also third party clamps can be used with the VML 1/4 - 20 mounting socket. No other inverter, to my knowledge, has either a stand mount or a USB port. If VML had neither it would still exceed all expectations or any non-existent competitor.
When you design an entirely new product from scratch is is difficult to predict sliding friction and every possible user application.
TheUSB port is an extra, added by the manufacturer. It is what it is and can't easily be changed. You can charge any USB device by plugging it's own charger in one of the AC outlets, or by using a suitable powered USB hub.
By all reports, VML is a fantastic and game changing product at a very low price, with as many WS per battery charge as any of the 20lb inverter packs, and close to 3 times the WS per charge as Acute and Ranger systems.
I will not allow this forum to become a slam Buff forum like the others. In time there may be improvements to VML, but do you want us to go into a 4 month longer delivery time for minor issues like this?
