For the price I was impressed. Everything I was looking for and had plenty of money left over for some quality speakers.

Don’t expect it to compete with $800 amplifier but for under $100 it’s definitely worth the purchase as long as your expectations aren’t unrealistic I would recommend for anyone looking to get more power out of their stock speakers or any basic speaker upgrade.
