Every bit as good as the name brand.
I suspect this is in fact the ARB device just without the logo since the parts are identical right down to the packaging. having said that, this is a fantastically put together system. The tubing is a bit stiff and a little difficult to work with as it has a mind of its own but overall, very good product, does exactly what it says it will and as far as installs go, pretty straightforward. self tapping screws could be a teensy bit longer. only a few threads are able to go into the panel.

Money saver
2019 tacoma. Some people didn't use the included nylon tubing but I had no issues. It took a little effort to get it on the differential nipple but it should be tight anyway so no water intrusion. I installed my breather behind the left taillight so I didn't have to worry about exhaust and heat damaging the line. Solid quality product looks exactly the same as the higher priced name brand product. Same some money, buy this. Worth

Nice quality
Update. Itโs installed and worked great. Installed breaker at a high point in the engine bay.....Have not installed yet , packaged in nice box. No instructions but itโs self explanatory! Once installed Iโll rate better or worse who know. But overall looks to be good quality.

Works well. Mounted aft of battery in 5th Gen 4Runner.
Hose is stiff, but avoids the possible $1-2k repair of differential or axle leak. Bolts can mount to factory threaded holes. Shark bite fittings are snug, but you can silicone the hose if you want to be overly cautious.

Bad hose almost makes it not worth buying
The hose is so bad it's probably not really worth buying this. As others have mentioned the hose is so hard it is nearly impossible to route it, and it cracks if bent very much. I had to spend another $15 to get some different hose. Also the cover on the breather falls off easily. I ended up safety wiring it on so I wouldn't lose it.

Good customer support
Kit fit well in my 4Runner and works fine, tubing was plenty flexible for me. I didn't get around to installing the breather until 7 months after I bought the kit, and then I noticed one of the holes in the aluminum manifold wasn't threaded well. I contacted the seller, and they sent a whole new kit, no problem. That's pretty good customer service.
