Ulanzi ST-03 Metal CNC Made Adapter Mobile Phone Holder Cold Shoe Mount,Cell Phone Tripod Holder Clip Adapter and Arca-Style Quick Release Plate for 4.3in to 7in Screen Smartphone (Red)

Perfect in every way EXCEPT one major design flaw. They forgot to include a 1/4" UNC screw hole on the exterior surface of this adapter mount (the side where the brand name appears). This would have allowed a perfect mounting place for lenses, small scopes, additional lights, mics, etc, etc to provide enhanced modes and capabilities for the phone camera.Examples of awesome mounting products that could have dearly used that forward facing UNC screw hole:- Lunies Mini Ball Head for HTC VIVE Lighthouses Base Station Camera Camcorder HTC 360 Degree Tripod Adapter Ball Head Camera Mount Holder 1/4 Screw 2Pcs- CAMVATE Super Clamp with 1/4"-20 to 1/4"-20 Screw Converter- Any other mount, device or attachment needing a 1/4" UNC screw hole!!!!Too bad!

I'm very happy with this product. The build quality is fantastic and it just simply does it's job well. One word of caution though: be careful tightening. The all-metal construction and machine threads are no joke. I'm guessing if one cranked down too hard, they might actually crack their glass.This item does have one design flaw though, the cold shoe. I rarely use mounted accessories so it's not much of an issue for me. But, if you're planning on routinely mounting say, a microphone when filming, you might want to look elsewhere. As designed, the tension screw knob sits directly in front of the mount. The result being that anything placed in the shoe is blocked. See attached pic, it's much easier to show than tell. Truth being told, I was still able to mount my Rode VideoMicro, but it was hanging on by a thread.***My Rating Criteria***Build Quality(47.5%) - 5.0 StarsEfficacy(47.5%) - 4.0 StarsPost-Sale Support(0.0%) - n/aPackaging/Presentation(5.0%) - 5.0 StarsWEIGHTED AVERAGE(100.0%) - 4.5 STARS

Really impressed with the quality. Holds phone firm and secure.

The sizing mechanism to fit your phone is the easiest clip I've ever used. Holds phone securely even in a thin style case. I've attched it to my octopus phone tripod with no problem.

Love this mobile adapter. I put a handle on the bottom and carry it around like a video camera for those great shots. I also put a light on the top that fits great into the hot shoe adapter they have there.

Good concept and well executed. Easy to pack.The only drawback is a lots of steps to set it up and take it down. A solid product.

Mounted V30 in a Love Mei case to a small tripod. Works well and seems solid .The reason for 4 stars is I have only used it once and the screw and guide look ok but time will tell.

Poorly assembled - one clamp that holds the iPhone cannot be fully opened.Disappointed with Ulanzi products (see also my review of Ulanzi Pistol grip Camera Holder)

Strong yet light with the cold shoe top mount option and bottom tripod mount
