The mechanism to adjust the IPD is a bit loose on mine but I should be able to fix that with a bit of Bluetack. I’m not sure what the minimum is but I know I have an IPD of 63mm and I have to adjust them about 3mm short of their maximum throw. IPD can be adjusted on the device as well. The lenses are fully adjustable and I was able to set them up to overcome my nearsightedness without having to wear glasses or contacts. I can’t imagine that a 7” phone/tablet with any sort of bezel at all would fit in here. While the description of the device on the dx.com website claims that it will hold phones up to 7”, I think my phone is about the biggest device you’d want to put in it. I would have preferred some sort of spring loaded mechanism. My phone is held in place surprisingly securely but I’m not sure how long the “ratcheting” mechanism which clamps down on the phone will hold up to repeated adjusting. Another issue is that the phone’s screen is completely enclosed within the HMD leaving you with no access to the touch screen (I used a keyboard and mouse sharing application called ShareKMS to get around this). My phone fits perfectly into the device, although the power and volume controls are completely obstructed. The lenses are much bigger too and, while I think the FOV is about the same, any distortion around the periphery is greatly reduced over the Dive. My first impression of the ColorCross HMD was that it was much sturdier than I had anticipated. A fact which I was aware of before purchasing but I was able to make some minor modifications to get it to work. One of the issues was that it was too small for my phone. I purchased the Durovis Dive a couple of weeks back and, while it was a neat first foray into the world of HMD’s, I wanted something better. In both devices, I am using my Samsung Galaxy Note 2. My first HMD was a Durovis Dive which is the only other HMD I've had experience with. I'm relatively new to HMD's so please forgive any terminology I may get wrong. I haven't seen any reviews of these online so I thought I'd share my experience with mine which arrived only yesterday. ack-336607) which, as near as I can tell, are identical to the 'NEJE LG-01 Universal Google Virtual Reality 3D Glasses for 4~7' Smartphones' which can also be found on dx.com (.
