I have one of the ESS branded safes.
It came with an instruction sheet that said "Brahma" on it. Mine was the B50 (ESS calls the ESS-50).
Definately made in China (it is labeled as such on the bottom of the side of the door).
Seems ok. Big, tall, roomy, lots of shelves, cut outs for two lags to bolt to the floor, opening to be drilled for a pass through for a wire for a dehumidifyer in the back. Seems to have a relocking mechanism inside, as well as a steel plate over the area where the lock is. Obviously not the same quality as the high cost American made safes, but this one was more than half the price of the big name brands.
The lock that came with mine was a mechanical dial. Works ok, but doesn't feel super high quality, it's probably the cheapest one they have available, but I'm sure you could have a better one put on at an extra cost. They said I could have an electronic one for $75 more. But they did say the electronic ones will fail someday, where the mechanical dials almost never fail.
ESS doesn't have these listed on their web site, but I saw one at a show and ended up getting a deal for less expensive delivery for one of the safes that was at the show. Since I lived not far from the show, and they were going to have to move it anyway after the show was over. I'm sure someone could have worked out a better deal. I had been putting off getting a safe for a while and decided it was time, so I went with it.
Here is a link of the same safe from a different company, but mine has a ESS logo on the door instead of the Brahma name and logo.

It appears to be the same safe, right down to the labels on the door.
Of course they have different sizes available.
Mine had a minor problem that I noticed after it was delivered. No problem, ESS came out and fixed it with no problem.
