Gebildet 2pcs 40/30 Amp Waterproof Relay Switch 12AWG Harness Set with Built-in Diode- 12V DC 4-Pin SPST Automotive Relays Hot Wires

The relay is somewhat bulky, but it's a perfect option for an underhood environment or perhaps even a marine environment. I'm using it in the engine compartment of my car. I'm happy with it. Works as expected.

All the wiring feeding the fuses is 10 awg. Relays are fed by 10 gauge wire also. This thing is worth the money. The 5 extra fuse spots are nice feature. These things are not really waterproof they're not sealed they have a top and a bottom so maybe a splash. If I need another of these relay/fuse boxes this will be the one I buy.....edit:I use these on side by sides I've had mine for a few months now I recommend if the panel is on something with vibration at least put a rubber dampner of some kind on the box the relays walk out of their holes. I put a 3/16 thick rubber pads under the mounting holes and replaced the relays with better 5 pin relays. The relays that come in the box are sealed relays but they're 4 pin. The 4 pin is all the the box uses but the more quality 5 pin relays fit tighter in the sockets

Works well. Bracket installation is optional. Waterproof and heavy wire leads.

Better than I expected. Not sure on longevity but it's powered my truck starter for a solid 6 months with no problems. Tight terminal connection. The wire ends are stripped for you but I noticed they are stripped just a tad too much and u have to cut 1/4 inch of wire for connectors. Other than that it works awesome.

Works as expected. However these things are unnecessarily large in dimensions. If you are working in a tight space like on a motorcycle these are really too big.

Hasta el momento funcionando bien

It works great. Can't beat the price. Mounting bracket on it is cheap, just be careful how you mount it

works well, all I need is one but will use the other ones someday.
