Good bang for your buck, great quality.
Works great. Most of it is metal and works as a heat sink. Came with two fuses and the adapters for smaller or larger Guage wires. Fit very well and easily for our choice of installation and was a great price.

Good for under the hood
Pretty good heavy duty block. It's got the rubber grommets for the smaller wire if needed.
