Works well but not perfect

The design of this is great. It really does channel all of my sweat away from my eyes. The only issue is using it on a bike. It works great for running because my head is straight up and down. When I use it on my bike (especially in aero position) some of the sweat runs over the front when my sweat rate gets high. Overall it works well but it's not perfect.

Works well, but it is just a tad difficult to program.  It also seems like it takes a little more force than it should require to lift the lid up.  I am hoping this gets better over time.  Overall, it is well worth the money for the convenience it offers.

The unit works well and was easy to install. It connects with one phone virtually immediately, and functions according to specification.

However, when one attempts to connect two phones, it takes a bit of fiddling to get both connected, but then when the power is switched off, the process repeats ie it does not consistently work with two phones.

The weakest link of the unit is the USB power plug which does not fit tightly enough into the cigarette lighter fitting and therefore loses connection intermittently. The second USB port was unable to power an older phone.

It works pretty well, it was a little tricky to figure out how to put it together. and mounting in the air vents is tricky as well.  it's not completely sturdy locked in as only one arm locks while the other piece kind-of balances against the vent grill at a lower spot.

Works a bit easier to place and remove my phone than the previous hold I had that was more of a clip design.

These work well, however the cover doesn't spring back 100% of the time when you pull out a plug. Sometimes it seems to catch on the outlet behind it.

Doesn't quite work as well as seen BUT just a few adjustments of seconds takes care of that problem and it is well worth buying it.

It works great, but I had to make some adjustments.  The first place I put it was on a tree about 25 feet from the main road and it picked up all the traffic going by.  When I moved it further in & on the other side of the driveway, I still had to make adjustment. I tented over the top and taped off part of the bottom and it works better.  But at certain times of day the sun sets it off.  So I do get a lot of false alarms. So until I see or hear of something better, for the money this works okay, that's why I gave it 4 stars.

Overall it works as advertised but the side to side and up and down movement could use some work. It really should be an adjustable "sleeve" that fits over if and adjustment bolts to better line it up straight. But it does what I wanted it to and makes attaching implements easier.

Works pretty well, but the holes to hang it from are not symmetrical and therefore it does not hang evenly.

Works well, not perfect, there is some noise.  It is not perfectly clear. The USB charger output is spotty. This runs down my phone's battery without replenishment.  Very disappointed in this regard.  The removable head is very handy when leaving the vehicle. Easily removed and attached without pulling the adapter out of the power port. My adapter port is horizontal so supporting the Mpow requires a little work. Clean design, connects to bluetooth easily, and is not to bright at night. (I prefer a dimly lit interior.)

My only negatives here are the functionality of the USB charging port and the challenge presented using a horizontal adapter port to plug for the Mpow.  Overall I am happy with this in as much as it has eliminated the need for CD's and expanded the availability of music and other audio to enjoy.  Kinda saves me from the format changes to talk radio on two stations which aren't swine stalled into a narrow repetitive selection of bland commercial music.

Works well, but it's a little less powerful than I expected.

It does what it is supposed to do. I reduced on star in the review. The reduction is due to the less than perfect fit. Its still a good tight fit but not exactly perfect.

Great but not perfect. It works well, the clip is well made and everything but a small tube of locktite would have made this perfect. The screws back out a little after firing the pistol but I bet some locktite would remedy the situation.

Works well. Occasionally I have to play with it a bit to get it to work but other than that it works well.

found that his product works as it should but the straw is somewhat difficult to stay. I don't necessarily need the straw for everything but would like it better if it was sized correctly. I am not sure what the problem is, but I am having a difficult time with it. I used it for my windows to slide up and down better and on a few hinges in the doors in my home, it is easier to use the straw to direct the product better but it will be more splattered about without the straw. This is a bit of a pain. I feel like the product works well, but is difficult to direct at the spot I need it to be directed at.

Works as advertised, but after several uses it doesn't seem to charge as long.

Works good but could be better. The ad cards some times will become loose in the case and the case is heavier than expected.
