Worth the cost
Color: Pink
Perfect holder for keeping hands free while driving. Ive been looking for a mount that wouldnt be permanently stuck to my car & this mount is it. It is adjustable & can be custom set to fit any phone. I have a samasung as an fyi. Ive been using it non stop, it doesnt block my vents & it can be turned if it needs to be. I will say the holder is stiff at first but once its set up it is simple to use. If your looking for a mount for your car with out it being permanently affixed & is reasonably priced this is the mount for you

Best Phone Holder I've Had
Color: Black
This is by far the best phone holder I've had for the money. It's economical and durable because I've had it for a while and it's still performing great. The phone is held firmly, and I haven't had issues with vibration. The only issue you might encounter is installing the phone holder to your car's vent because vents are different sizes and might not be a good fit. I had to adjust the metal piece to go behind the vent in order to make it hold securely. That issue is because different car manufacturers make their vents different shapes and sizes so it's understandable. Overall, I recommend it for its functionality and fair price.

Well worth it. Great product.
Size: 1 Kit, Size: 1 Kit
For the inexpensive price it’s worth its weight in gold. I admittedly probably didn’t work on it as long or as hard as I should have, but I still had great results. *** One warning: when it says to “tape up and cover your paint around it” do it! I figured I would just be careful but no I was wrong. It will REALLY damage your paint, so make sure you don’t get any on it. YES- This is the sanding discs too! They have chemicals on them, they are not regular discs. If you do get on paint, clean immediately! My only regret with this project and my fault, not theirs. My headlights went from dingy yellow, to much brighter and definitely more clear. Love the results. Very happy with the purchase.

Great for the price
Size: 1 Kit, Size: 1 Kit
Worked great at clearing my headlights and at a great price, I had used a different headlight kit maybe 5-6 months before and it did not perform as good as this kit did, maybe it was a user error with the previous kit but this one cleared it easily and was very easy to do and had a nice clear shine.
