Hi, Germ! Sorry, but I don't own a digi-cam, so I'm unable to post pics of any kind. I can give you some size differences for reference, however. With the head of the Hard Case pivoted up (like a "regular" flashlight), it's approximately 2" longer than a standard MiniMag. With the head pivoted forward (angle-head position), it's approx 1 1/4" longer than a MiniMag.
The Hard Case doesn't have adjustable brightness settings, just multiple colors and IR. All of the switches except for the IR switch are silent forward clicky switches. For the IR switch, refer to ernsnada's photo above. There's a rotating ring just above the heel of the light, and a sliding lock on the back of the heel. Simply slide the lock down and rotate the IR switch to the "on" position. By using the main beam's on/off switch, you can cycle the IR between constant on and flash. The switch for the main beam is on the base of the light. There's not much tactile feed-back on the switches, but for a "tactical" style utility light, there's not supposed to be.
All colors (except for IR) can be turned on either individually or all at once. Since I primarily use mine in the angle-head position, I sorta wish the main beam switch was on the front of the light like the colored LED switches, instead of on the bottom. For a 2XAA light, the Hard Case is somewhat bulky, but it's very lightweight and extremely "tough".
To me (and I'm sure others will have a different opinion), the Sidewinder was a total disappointment; from the quality (or lack thereof...) of the 5mm LEDs, to the ackward way of changing the color of the LEDs, to the virtually useless beam of the white LED's stock optic. If you're wearing gloves, rotating the switch to change the color of the LED can be a real PITA! From a "size" standpoint, I'm sure a lot of folks will prefer the Sidewinder. In the angle-head position it's approximately half the length of the Hard Case, and can fit in a hip pocket quite easily. Again, to ME, that's the ONLY advantage the Sidewinder has over the Hard Case. Given my "d'ruthers", I'd rather be toting the Hard Case on my belt than the Sidewinder in my pocket. Also, on the main beam the Hard Case is EASILY (...and I mean EASILY!) twice as bright as the Sidewinder, and has a much better tint. The Hard Case's tint is a nice warm white, while the Sidewinder has a VERY noticeable blue tint. Last of all, the Sidewinder has no capability for "signaling"/temporary light. The light's either turned on, or it's turned off. To me, that's a MUST for a "tactical" style light.
If it sounds like I'm a "little" biased towards the Hard Case, it's because I AM! IMHO, it's simply a superior light in almost every aspect. YMMV...
