Will almost certainly not be your audio quality bottleneck.

In short: This lapel mic is absolutely excellent. Don't be fooled by the low cost. Read on for some expensive lessons I've learned over the last 4-5 months:
I have been experimenting with a Blue Yeti, a Zoom H1, a Rode VideoMicro and now this lapel mic. I have been using those microphones/recorders directly, and also plugged into my Huawei GR3 phone, the audio input of my Nikon D7200 camera, and the audio and USB inputs of my laptop.
The distance from the sound source to the mic is TWENTY time more important than the quality of your mic. If you can get your mouth within 1 handspan of the mic you are doing ok. With a lapel mic, you can be closer than that. I can't emphasise this enough - it was impossible for me, with a range of devices, some of which are quite expensive and sought after, to get a good result without being literally on top of the microphone. Hence my looking at this lapel mic. I should have bought it first!
With a shotgun mic, it's very difficult to get high enough audio levels without cranking up the camera pre-amp and that introduces tons of noise. For my D7200, vol 8 out of 20 is about as high as I want to go without introducing extra noise from the preamp. Leave it at 8-10 max, and it's easy to normalise that audio later in post processing. With the zoom h1, the sweet spot is 40-60 input level.
if you're using an Android phone, ditch the built in recorder app and go for something decent like the ASR app, and go through the settings, and set it up well - it will record in high quality wav format, and you can turn off all the features like noise reduction and so on, and do a better job in post processing with audacity.
In short, for my needs, this lapel mic and a phone are acceptably good. This lapel mic plugged into the camera or zoom sounds absolutely excellent. Wish I could have found this information before I started!
