This is an amazing piece of equipment.
The main feature of this tuner is the polyphonic tuning: you just strum all your 6 strings at once, and the tuner shows tunings of all strings simultaneously. This saves you a lot of time.
I am still quite a guitar novice, and tuning always feels like a chore, so I often skipped it. With this tuner it takes just 5-10 seconds to make sure you are still in tune, and the subsequent tuning is also pretty quick, so you are not tempted to skip the tune check before practice.
Of course, it also has a normal "needle" mode, and the switch between the two is automatic (strum 1 string vs. strum multiple strings). The display is bright, and the visuals/animations are nice. It's not an LCD display, but I like it: the dot-matrix display gives it a somewhat "retro" vibe. The clip strength seems OK. A battery is included too.
It also has some advanced features: tuning for bass guitars (albeit no polyphonic mode here), up/down tuning + capos, and different reference pitches. That's way too complicated for me just yet, but I can see myself using capo tunings in the future.
The only "downside" is that this tuner is expensive (35 EUR), but if you are short on money, and plan to upgrade to this later, I would suggest to use a smartphone app for a while, and save up for this unit.
