Mickey, good. Thanks for the question. Yes, you're right, E3 is a little bit out of the norm for us in that regard. What they do, though, they mainly provide a -- I call it, a product that goes mainly to the guys that do the fracking. So if you understand where you go from the well to the pipeline coming out from a fracking situation, you have times when these valves that they have will basically -- the pressure gets too high and they sought to blow, right?
And the way they mechanically do it, have done it for many, many, many years, is literally have somebody take and go internal ranch and relieve a valve and it can be very dangerous. What these guys have developed over the last number of years is a system that sits on a skid about the size of a decent-sized table, if you will, that actually control electronically. So it understands pressure building and has a relief. And they've got some technology in the valve system itself that allows for, I'd call it, some proprietariness to the system.
So they are really in a position where as long as you're doing some of the fracking and unless that business completely went to 0, they're going to have -- still have a very substantial opportunity.
They rent their product. The payback literally is like less than 4 months on what they rent, and they are building them as fast as they can make them. So that's kind of a high level. And you're right, it can be cyclical, but given the profitability, given the level of cash that they have, we believe even if we had somewhat of a slowdown, we would be in really good shape going forward.
It's a pretty unique situation, frankly, and by the way, run by very experienced folks, and we went out and brought in some very experienced management to the deal guy came in from Halliburton, who is the actually CEO. We brought him in. So I think we've got a really great management team that knows the industry.
