Default eBay inline ball and spring MBC

So, I've been looking around for cheap boost control (I ended up getting a retro dual stage MBC), and I found this:
Manual Boost Controller MBC Adjustable 1-50 PSI CNC Machined Ball and Spring | eBay
Has anyone ever used this? Heard anything about this?

Search for "NXS MANUAL BOOST CONTROLLER" on eBay and get that instead. I have been using his MBC's for years without issues.

Looks just like the ball and spring one I built from home depot piping parts, worked pretty well! It blew apart however and home depot stopped carrying the parts I used.
I got a used TurboXS dual stage. I don't plan on using the dual stage feature really, but it was cheap, and seems to be solid.

The ball and spring MBC is fairly easy to piece together with a trip down the hardware isle. It functions like a second wastegate upstream in between your intake manifold source and wastegate port.

You can even mount the piece in the cabin with a wingnut or **** on it if you want to turn the boost down on the fly. This is not the same level of control as a dual port wastegate, electronic boost solenoid and ECU control, but a regular one port wastegate with a simple MBC like this is the cheapest simplest effective method of boost control which shouldn't be underestimated IMO. If you can get all the bells and whistles to work with EBC that is a definite advantage but this simple method absolutely works. By design it may help spool too but I haven't measured it.
Another fun idea would be to use an ECU controlled stepper motor on the adjustment nut, super DIY EBC?

Although honestly, I've been looking for way too many alternatives to a DIYAutotune EBC. I should just pay up for theirs instead of messing for hours.

Like the one I linked to, or the one created using pipe fittings?

He had one like the one I linked to. I am just lazy and finding all the correct parts to build one yourself can be hit and miss. I think I was at about $10 in parts to build my own then you add in time going to various hardware stores and such to find the parts.
