This guitar is not q good value. The target audience is new players who lack the knowledge and expertise to realize that the so-called "String Science" violates the integrity of the guitar. There is nothing unique about the Zager which makes it inherently easy to play, it is simply an Asian import guitar that has had a technician (Luthier) set the guitar up for extra light strings and shave the braces to thicknesses that are unsafe with regular gauge strings.
Any guitar can be made to play exactly like a Zager by simply taking to a skilled guitar tech (luthier) and requesting the same mods. Depending on the part of the country you live in, this is going to run between $50 and $100. The math is easy - you can get a good Asian import and have it set-up and be Hundreds of dollars ahead!
The advertising hype is hard to swallow on this guitar. Reminds me of several sayings: "if its too good to be true, it probably is", and "Theres a sucker born every minute" come to mind.
So if you just want to buy a guitar with the lightest and lowest strings possibe, and don't care about the limitations caused by the alterations, then this is the guitar for you. But if you want a better sounding guitar, at a lower cost, and without limitations, then buy one of the many excellent bargains from Asia and have a Luthier set it up for the lowest possible action with extra light strings (Without changing the bracing or frets!). You will be able to revert back when you decide that you want more tone from your guitar, and you will be money ahead!
