works ok ...too refllective

A little too reflective for my taste, wish it were more semi gloss

The product works as advertised, but I can't say it's an amazing product. First, the controls aren't intuitive. Because the same set of four buttons control each bay, you need to toggle to a certain bay before you can change the settings. It would have been better to have separate buttons for each bay and shrink the excessively large LCD screen. There's also a discharge/refresh function that took me some time to figure out (is it discharging or refreshing?) I guess it's discharging to refresh, but it also charges when it's doing that, so why not make it a charge/discharge/refresh option to make it easy to understand?

I can't expect too much accuracy from a $30 product, but it gave me a null reading on one of my batteries. I was going to throw the battery away but saw some other reviewer comments and charged the battery in a quick charger first. When I put it back in this charger, it correctly charged, because the initial voltage was too low. It's not a good sign when you need another charger to get this charger to work. For the quick test, it gave me a very high resistance reading for one of my batteries but when I tried it in another bay, I got a much lower reading.

Came to me with discoloration or dirty spots. It's humongous. Seems to work decently. It can buy you about a half hour.

This works great for most Digital to Analog. However, you will get the loudest, and most disturbing clicking/distortion when attempting to use this in a way where it's processing OTA HD signal.

It will work for amps, PC'd, media PC's, etc. Using this for Broadcast HD will not work. Period. While I am rating this three stars, my opinion of it is more 2 1/2. It works...but I would have preferred something a bit more robust.

The device works ok .  Mine is primarily used for books on tape going to/from work.  I do have to search for frequencies with no static.

A main complaint is that the LCD displayed frequency is at an angle that makes it very difficult to read from the drivers seat .  I have to stop, exit the vehicle then bend over the driver seat, looking at just the right angle, to see the display and determine what frequency I am using .  The presets help but if you hit the wrong button then your back to reseting up the whole thing.  I thought having the transmitter part condensed into the power adapter was a good thing but now wish I had used other products that have the transmitter midway in the line .

Used my son's Monster iCarPlay Wireless Plus FM Transmitter/Charger for iPod http://www.amazon.com/Monster-iCarPlay-Wireless-Transmitter-Charger/dp/B000H72MMU/ref=sr_1_10/002-0007412-8138438?ie=UTF8&s=electronics&qid=1192051263&sr=8-10
and find it a much better product .  Less static.  LCD easy to read .
If I ever replace mine this is what I will buy next.

works good but can't get the contrast does't seem to work,  I have tried to adjust it a whole lot of times. it just won't get any brighter. most of the time its hard to read.  any suggestions????????

This charger works well, but I have an issue with the blinding blue light it emits.  I had to put a piece of electric tape over it because it was illuminating the entire room.

although the adapter works well enough, it is rather cumbersome when you forget to recharge your MB book light and have to use it while reading.  I might move forgetting that I have it plugged in and bam the light goes out.  I also found that the end of the adapter that plugs into the light fits but not snuggly enough so any movement however slight with mine tends to turn off the light.

However the good news is that the Mighty Bright Light does not suck up regular battery powers like other readers.  Believe me when I say that I have bought all types of book lights from Target, Amazon (sorry) and Walmart and no matter what they claim, they are not bright enough in a dark room and they require so much battery power and lose it quick that you have to buy it in bulk.

All in all, not a bad idea to invest in an AC adapter for a Mighty Bright book light for those occasions when you run out of batteries.  Just make sure that when you receive it, that it fits snug in your Might Bright light.  I did not ask for a refund or return from Amazon since I don't have to use mine that often since the batteries last.  If I had, Amazon is the best in refunds and exchanges.

Nice price, and overall, it works anyway...But keep in mind that this filter has too stiff rotation, so you may lose the perfect shutter chance to adjust it. Compared to Carl-Zeiss CPL, the elimination of reflection is also not so dramatic.

Works ok for macro photography. The LEDs are quite blue and push the limits of my camera's white balance. The orange filter is too orange. I had to search through other user's reviews to figure out if the DC adapter should be tip positive or negative.

good construction but the mirror of this adapter make loose more stop of light ... i use it with canon 50mm 1.8 indoor and its impossible to have good  balance exposure/iso (grain) without additional light... don't r&eacute;comend it ... too expensive

it does the job, but it doesnt do the job well. its not a sharp reflection, i figured that it would be a strong refelction, the adhesive side has more reflection then the plastic side.

It does what it is designed to do... however, the volume knob was super sensitive in our scenario.  Purchased this to install it in-line with my father's hearing aid transmitter for the television.  Without it, the volume level damned near blasted his head off.  With it installed, the volume was attenuated, however, we had to turn the knob all the way to the off point, and then barely tap it to take it off of the "off" position.  I expected more granularity in adjustment.

On the one hand it fits a need, I'm using several of these to balance different color strips on a homebrew plant light.  I wish it came with some sort of instructions or datasheet - I had to open one of them up and reverse-engineer the circuit to determine the current rating (1.5A looks reasonable, can do more if in a ventilated area [it's 3x 1.5A FETs in parallel]).

Also would be nice if the button operation made sense.  The labels imply one is on/off, one is intensity, and one is blink pattern.  It doesn't really work like that, and I'm still at a loss to explain just how it does work.  I ended up just mashing buttons until what I wanted to happen happened, and left it that way.  Which is OK for my application.  Important part is with an upstream switch it remembers its last setting, including on/off and intensity.

So 2 stars off for lack of documentation, otherwise a decent product.

Works well, but not as good as&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Antec-Bias-Lighting-for-HDTV-with-51-1-Inch-Cable-Reduce-eye-fatigue-and-increase-image-clarity/dp/B007TG5EG8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Antec Bias Lighting for HDTV with 51.1-Inch Cable (Reduce eye fatigue and increase image clarity)</a>
My tv is able to power the antec off its usb port where this vansky one needs to use a wall plug, which means i have to manually turn them on/off

Ok, these work.  However, the sensitivity is not that great.  It's either "super" sensitive - or not sensitive.  The light level shutoff is also not that good.  However, it does work, although not perfectly.  (One in a closet - no sunlight works the best.  The one in the garage where I wanted to adjust sensitivity and light level works, but is more than likely to turn the light on regardless of how bright it is outside...)

Nice unit, plan on using AC power for the base.  Works as it should.

Works best if base is wall mounted (low) or your eyes are above the unit.  If you free stand it leaning back (in the base provided) and you eyes are even with it elevation wise contrast is POOR.  Works best if  leaning forward which can look goofy...
