They have two types of two-way rods, one called "Two Way" like the one you linked to, and another called "Dual Action". I've used the Dual Action ones on guitars, octave mandolins, and mandocellos and I like them.

I have not had a problem with one yet. And I like the price.

I have bought those from him and have been very happy with them.

Blanchards are the Cadillacs but pricey.

What Terry said I used the Blanchard rods too nearly 20 years ago and they are still performing like they are brand new. I have hernias and truss rods get corroded and stuck so it's really nice to not have to hurt myself to adjust a Blanchard truss rod their action is the smoothest in the business. By the way "smooth" when it comes to stuck truss rods translates into predictable results for the neck making them easier to use on a number of fronts.

I would be reluctant to use an off brand truss rod a failure here and historically there have been plenty of rods that failed a failure here can pretty much take an instrument out of service and if the economics of a very expensive repair are not there it can be the end of life for a instrument. An extra $20 on the truss rod can save hundreds later in life.

Don't know if they are available to the public yet but the rod Martin is using in the "modern" designs with a 4mm adjustor is also excellent. And the Martin 5mm rod that they have used for some years now that is two way is also excellent.

Of course I would also recommend no matter what rod you use clamping it in a vice and cycle it several times paying attention to the welds on the adjustor. There is an infant failure rate on some rods and you may be able to catch a bad one in the testing stage.

Back in 2009ish one of the most popular rods from a major lutherie supplier had a bad batch of welds on the adjustor. A lot of them failed and it caused a lot of tears.... At that time there were two suppliers and even though their rods were different they looked nearly identical.
