mine broke after about 1 month, its not meant to be put in and out of cars. I was switching it in and out of 2 vehicles and it broke.. unable to repair it. great if you plan of leaving it stationary.

Works great for around town, but don't buy this model for recording track videos/autocross, etc.  It vibrates the phone video under harsh driving conditions

I use these in my 18 wheeler to hold up my ipod touch when drivin and they worked great for about 2 weeks then my ipod started to sometimes fall off when driving. So maybe it's better for cars where it's not placed on a vertical sloop.

I got this mainly because i was little afraid to open the weather sealing to run the av wire from the backup camera. It is good while watching video in stable environment. It worked nicely when i tested this in my parking lot. But while driving, it worked good most of the time but i was able to see lines and red tint in videos at few times. Pay little extra to a mechanic and run wires under the weather sealing of you car and get a good quality video(I did it myself after watching YouTube videos). I really don't want to sacrifice video quality for wireless feature. I returned it and got full refund.

I bought this for use with my Galaxy S7. The good news is that it works great. The wireless charging works as expected and it holds my phone nice and tight. The bad news is that I couldn't find a way to mount it in my car without it either tapping against the windshield or tapping against the dash if mounted on the windshield. The one thing I could do is turn the phone into a landscape orientation, but I wouldn't be able to rotate my phone then. Sadly I had to return this device and I'm going to opt for a car mount with an arm instead of a fixed mounting point.

Purchased to use as connection between cell phone and auto dash board for Android Auto.  Most cables are too long so this seemed to be a good choice.  Problem was that when connected Blue Tooth connection to vehicle stopped working.  So there must be some problem with the internal wiring.

Nice for small jobs but not for driving large crews. Battery life is very good even if not used for quite awhile. Single speed only.

Worked well, but did not hold up traveling, after taken on a few trips it no longer works.

worked great in my vehicle.  I used youtube to make the repair and it worked out fine.  not very mechanical but I figured it out

This works pretty good in the city when no near power lines. Should I take a long trip I will change back to factory antenna.  I do find I lose my HD signal more with this part.

worked great until i went to get out of my car with my phone still plugged in. It kinda pulled to cord hard and it never worked again. My fault but these types of cassette players are never very durable. I've owned one for every vehicle I've owned until I could afford a new stereo

They worked very well but they are not for outdoors use even though they are advertised as outdoor cameras. I have set one and it was ruined after a week.

I use this as a windshield defroster on my boat, and it works excellently for this,

BUT I cut that 12v accessory end off and attached it directly to the battery on the boat, using 12 AWG multi-strand wire and putting a 30 amp fuse in line.

Plugging this into your cars cigarette lighter will yield disappointing results and probably break your cigarette lighter.

-------------------------------------------

This item attempted to light itself on fire, and was smoking considerably.

The odd thing was it was not turned on.  It seems the front switch on the panel spontaneously decided to light itself on fire while the device was turned off.  Fan was not spinning, no heat coming out.

Down rated it to one star for self ignition.

Tried to use this with a motor home, kept loosing the connection between the unit and the controller, almost caused an accident, maybe it works with a shorter vehicle
