Question: How loud are the speakers?
Document: Can't even use the second screen because the feedback noise is so loud
I was very unhappy with the product. It played about 45 minutes of a movie (using the car adapter) and then froze. I tried restarting it and it froze loading of the movie. I tried a second movie. Same result did not play the movie. When we got home from our trip I tried to use it with the plug in adapter. The main screen made a loud buzzing noise and still froze as soon as the movie loaded.
We received this player as a Christmas gift. We installed and used it for about two weeks, when the main screen got blue/gray hazy lines over the movie playing. The other screen continued to work. Amazon is wonderful about returns so we had no trouble getting a replacement. The second day of using the replacement, the additional screen just went black and a loud squeal started. We checked cords and even replaced the AV cord, to no avail. Seems like we received two lemons in a row.
cheap, light, speakers didn't work on the slave unit. audio was way to quiet. even with the volume maxed, you could not hear it in the car. The quality of the picture was poor. We moved to this after having a Sony 7&#34; player, and this one is way lacking. Going back to Sony 9&#34;.
this is exactly what i expected. came on time original packaging. and it works perfectly my 4 year old love it when we travel, even my 15 old month baby enjoys it. plus the advantage of the usb/sd card it is really a plus...
the sound is okay.... the drawbacks are the criss cross straps that go on the head rest, (not very neat looking) and when we go on drives with kids,,,, which are never the length of a movie. getting back into the car you would like to have the movie start where you left off..... like 35 min into the movie ... nono it starts again from the beginning.... annoying
seriously no battery!!! And it is a portable electronic device? By that criteria the $20 DVD player you can buy in the clearance aisle of Best Buy is a portable DVD player. Sending this one back!
came on time and met the expectation it does not play quite a few extensions so please be aware of it
bought for grandchildren, may need to buy a set for myself. Works perfectly. Easy for the six year old to use
Wow, words cannot describe how much we hate this player. Took a chance based on the good reviews and have regretted it ever since.Sound and video quality are decent, though we set it up on the counter to view them before we went on a road trip and one screen is a slightly different color and not quite as sharp, red flag number 1. Turned on a test movie to make sure we knew how to use it and it took FOREVER to load, red flag #2.
Answer: The speakers are loud. I never turned the volume all the way up because that would be way too loud. Love this product!
