Perfect diagnostic tool
This is one tool I don’t want to be without when diagnosing a vehicle. I’ve had other relay tools but this is the one I reach for first. Great tool

Good quality
Very good quality relays, the switches seem very firm and robust.Some of them might be slightly bigger or thicker than the relay your replacing with.

Brilliant piece of kit.
One of the things that I like about this product is that most of the more commonly used relays are included in the kit.I use this kit to help me diagnose electrical circuits on motor vehicles.

super handy
used this to prime my trucks engine after an oil pump change and coolant drain. simply replaced the starter relay with the one from this kit and turned it over multiple times while no other systems were on.

As a diagnostic tool for cars this works great !
Super simple. Exactly what I needed to find a problem which was difficult power drain issue. Very good product. Worked without any problems at all.

This should be in every technician's arsenal
There are larger and more comprehensive relay circuit testing kits out there (like Lisle's 69300 Master Relay Test Jump Set or AESWave's uActivate Master Kit) but if you just need to bypass a relay and power a component at the fuse/relay box, this kit has everything you need for quick and easy circuit testing.I have used this kit many times in the shop since purchasing it to test fuel pumps, starters and other circuits where a relay is used for component control. Simply inserting this relay into the appropriate cavity in the fuse box and activating the switch can immediately give you a path to take for your troubleshooting process. Before it, I would just use a pre-wired inline fuse holder with spade terminals crimped to the ends of the wires, but this is simpler and ensures you have a good connection in the fuse box.I have encountered the odd situations where the design of the relay and/or the fuse box would not allow this to be used (the OE relay and cavity are a bit too small for it to fit) but it does not happen often and most times I can use this kit with no issues.
