[11.8" / 30 cm] This product is a new toy for me. I have a few cameras but nothing like this. I found it much more easy to handle with a mini mondo stick while only useing the wrist lanyard. Useing the zoom feature, movie and photo buttons were easy but to read info on the screen , with goggles on, was impossible, so it was a case of set and forget. The camera took good photos and movies but I would only use it in this houseing for underwater use. The down side is the houseing needs “sights” to lineup subjects,and the filming light needs to be brighter or bigger or maybe a different colour so it is easier to see .I got about an hour of use from the battery which is OK seeing the camera is continually on and working the zoom. All up, it is a very good unit snorkeling and shallow diving. With more practice this unit will shine in a new world.

[0.45 lb] I usually use a longer arm of the same design, and really like it. This arm provides utility in some diving situations because of it's shorter length. There are several nearly, if not exactly, identical arms out there, and this one is less costly, so I rate it even higher. This is not the same as some arms called loc-line arms, and the loc-line arms are not as strong as this one. This arm is easy to use with DIY trays.

[0.45 lb] Best arms out, very well made.

[11.8" / 30 cm] Perfect fit for my Olympus case, solid lock. Provides good angle of flash.

[11.8" / 30 cm] As alway, B&H came thru when no one else could. These days, it's hard to get parts for my underwater camera housing. B&H came thru.

[11.8" / 30 cm] It's about what you expect. If you have the Flex Arm and the new Cintiq Pro 27, then you need this for it to work. Easy installation, just screw it onto the Cintiq, slot it onto the arm, screw in the bolts, and you're good to go. Surprisingly heavy, weighs literally ten pounds. Price is painful though, would have been happier with half price.

[11.8" / 30 cm] The Impact MC-03 Magic Clamp not only is very useful for desks, but also very useful for bed frames! This is going to be my primary use, watching YouTube and movies hands free while I lay down facing up nice and comfortable with my pillow. 

This reduces fatigue holding a phone in bed for hours and trying to watch my content sideways and still having to hold the phone. Not anymore!

The gooseneck is made of metal, everything else is plastic.
There are two types of people, the ones that break everything they touch, others who like to add a little finesse handling things.

The ABS plastic is a hard plastic material, so the plastic clamp that attaches to surfaces, I find it sturdy, has a strong bite.

The phone holder being made of plastic, even loading with a heavy iPhone ProMax, it holds the phone fine, there is NO NEED to over tighten the ball mount. That is the ONLY part that requires a little finesse. This in my hands will last a long time.

Yes, it would be nice if the whole unit was made of metal. but it's going to cost more of course.

Pros: 
1-Very flexible (and metal) gooseneck, and even mounting in a bed frame which gravity will want to pull the gooseneck down, it stays!

The phone holder can tilt a little, allowing minor adjustments to be exactly parallel to my face mounting it on my bedframe frame and at a perfect height.

2-Clamp has a nice bite.

Cons:
1- Phone mount plastic parts may be a little fragile for some users.

Just be gentle with the phone holder ball mount and you'll be fine. You do NOT need to over tighten.

[I have received this product in exchange for my honest review]

[11.8" / 30 cm] Everything about it is exceptionally well made.

[0.45 lb] Works as designed & described. Once set up the peer are several tension adjustments at various points of swivel and rotation. Can adjust to your preference and mount is stable to allow touch input on screen without moving the mount, yet still flexible to make subtle position adjustments without need to loosen tension screws. Great product.

[11.8" / 30 cm] Perfect for my diving photo gear, did not have it in stock, but send it over very soon.
