It's a good HU the only thing i dont like is when using a USB the seek time is really slow.

This head unit is really impressive. Especially for the price. It puts out really good sound and its easy to use and the install was easy. I would highly recomend buying this head unit or any other Alpine head units.

Entry or high end Alpine always delivers and this unit is another greath addition. I've had the cde102, cda105 and the cda9886, I love all of them, and now this is my 4th alpine, first alpine I had cde102 I upgraded to the 105, then 105 got stolen then found 9886 in a pawn shop and with no hesitation bought it, then sold my car that 9886 was in an it was all she wrote, and now I have th cde121 and wow the sound difference between my 99 chrysler concorde unit was a lot. Alpine clean and clear power totally recommend.

This stereo is awesome! it was easy to install and to use, no difficult controls like some head units have. Makes your speakers sound amazing, you cant go wrong with alpine.

It's an Alpine, Enough said. Only headunit brand i will ever buy. Owned for 6 months now, been in two different vehicles. 5star.

For the price you are paying, this stereo goes above and beyond expectations. Although I'm not suprised since Alpine is a very trusted brand. The sound quality improvement is enormous and it puts out a decent amount of power, nothing that'l blow your ears off but definitely very loud. USB and aux ports very convenient and the player itself was a very easy install.

This deck has more then exceeded my expectations... Its been durable and given a great performance. I would Highly recommend.

The only thing i can say is its the best choice on a budget.
