Overall I would say this is a good car mount. There are a lot of nice features, although there is one glaring issue that prevents me from giving this a 5 star rating.My last phone mount was great until the spring holding the suction mount broke. That left me looking for a viable replacement. My criteria was:1. It had to offer solid dash mounting on a rough dash surface.2. It had to be easy to insert and remove the phone3. It had to be fully adjustable so as not to block my field of view.4. It could not block or interfere with any of the phone features such as charging port, volume or power switches.This mount met 3 out of the 4 criteria perfectly.As far as mounting and mounting options, this mount is stellar. It comes with both a suction mount and a vent mount, both of which work extremely well. The suction mount comes with a round pad that you can use if you are mounting on rough or textured surfaces. The pad glues onto the surface, and the suction then mounts onto the pad. Fortunately even though my dash is a rough surface, the suction alone was enough to hold the mount in place very solidly. The vent mount has a nice locking feature that keeps the mount held in place on your vent slots. Overall I would give the mounting system a 5 out of 5.Inserting the phone was really simple. There is a small protruding "ledge" at the bottom which supports your phone, and allows you to balance the phone on the ledge while you adjust the side arms. The arms lock into place and hold the phone very securely. The arms are also padded so they will not mar your phone. There is a small amount of overlap onto the side of the screen, so depending on the apps you use, this could create a problem. If you routinely need to access the side edges of your phone's screen, this could be frustrating. Inserting the phone with one hand receives a 5 out of 5 star rating.Retrieving the phone was were I have the biggest issue with this phone. For most people this might not be an issue at all. Due to the contours of my dash the only place I have to mount the phone is just right of the steering wheel on the dashboard. For visibility, this is fine and I actually like the location as it provides for easy one handed access to the phone without me having to venture too far from the steering wheel. The problem is that the release tab is on the left hand side of the mount which means I need to reach behind the steering wheel in order to hit the release switch. It forces me to contort my wrist in a way that most human wrists do not bend. I'm forced to hold the phone with my right hand and use my left hand to reach behind the steering wheel to release the locking tab. Most other phone mounts that I have used have either release tabs on both sides of the mount, or a release tab on the back of the mount. Releasing the phone gets a 1 out of 5 stars.Adjustability on this mount was also great. The mounting arm can move up and down, in and out, and the mounting ball allows for full rotation of the phone. This system allows you to adjust the phone to almost any possible position. Movement was a bit stiff, but that is what you want so it doesn't start sagging on you. The position of the lock wheels and adjustment screws was a little difficult to reach, but really you should only need to adjust it once or twice. I've seen better locking mechanisms on other mounts, but this one is plenty good. Overall I would give adjustability a 4 out of 5 stars.The overall design was well thought out. With the exception of the release tab, everything fits just right. I'm using a rather large phone (oneplus 8t), but I also tested with smaller phones like the essential phone, and it just works great. Nothing is blocked and you have full access to everything you need. I will say if your phone has a bottom mounted headphone jack there could be access issues for that. The little ledge does cover a good portion of the left and right sides of the bottom of the phone. Top mounted headphone jacks of course will have no issues. Also the opening at the bottom should be large enough for most USB plugs and dongles.So to reiterate my initial comments, this is an excellent mount. If it wasn't for the poor placement of the release tab, I would give it 5 stars. If you mount you phone more towards the center of your dash, or if you are just going for the vent mount, this will not be an issue at all for you. Also if you have a bottom mounted headphone jack that you need to utilize, you may want to look elsewhere.
