I bought this product as it was one of the cheaper chromatic tuners on the market. I was a little worried that it wouldn't match the quality of the higher end tuners but was surprised at the tuners accuracy. I use it on my acoustic guitar and mandola (requiring a CGDA tuning) so the chromatic mode comes in handy. The ability to change the frequency is also useful if you want to tune slightly sharp without snapping your strings or use alternative tunings.
I would recommend this product to anyone who is looking for an efficient tuner but who is also low on money. The only downside is that the screen isn't very bright so would advise against using it at night.
