I wish i had gone with a pedal tuner. The only reason i didn't was because of the included microphone, but it doesn't work very well. I'm now planning to sell this to get a solid pedal tuner to use in conjunction with my aftermarket tuner pickup, which is the only stable way to tune an acoustic that i've found. If the extra features are really that important to you then this might be a good purchase, but i was pretty dissatisfied with the quality in general.

Sound
Doesn't seem to affect the signal chain, although i try to run mine through a tuner out when possible.

Features
has a nice variety of tuning options, though most aren't really necessary once you get past simple chromatic tuning.

Ease of Use
Tuning stability could be better, especially considering the price. Honestly, my 30 korg tuner is no better or worse in terms of tuning stability. I had hoped the analog needle would give a more accurate read, but it doesn't really seem to. The mic isn't that useful for tuning an acoustic, as i had hoped it would be. I ended up having to buy a "tuning mic" for $10 afterwards, which now makes tuning the acoustic much easier.

Quality
Overpriced, overpriced, overpriced. It works, and it works fine, but so do most tuners that cost half this price. The plastic feels cheap, the design doesn't feel especially intuitive, and it doesn't seem like it will hold… read more up in the long run, and for this much money i had hoped for a lot more. Not very useful for tuning an acoustic guitar.

Value
Like i said, far overpriced. shouldn't cost more than $40 or $50, at most.

Manufacturer Support
i'll give them the benefit of the doubt, since it hasn't broke yet, i have no experience with them.

The Wow Factor
Purely practical addition, probably should have chosen something else.
