Bests & Worsts Reviews from Amazon

Being an engineer and technician I have no problem with these little devices. They all are cold on one side and hot on the other side of the device. They all have a little cheap fan running to remove heat from the hot side. Without that fan they will not work! Changing the fan is easy and cheap versis throwing away a solid state device that is working fine, just in need of the fan. You can get these fans in most electronic stores. You can buy them all over the Internet. You might even find one that will fit it in a computer store like Fry's etc. These fans last a year or two and the bearings lock up. Don't throw away a $50.00 item for a $5 to $10 fan.
