Eventually, the buzzes got so frequent and annoyingly inaccurate, I have now been subconsciously trained to just ignore the buzzes like I ignore my alarm clock in the mornings

The buzzing gets annoying, but that's the whole point

The buzzing can get pretty loud

The gentle buzzing really does help keep me from slouching

delay (feedback delay makes the Lumo 'buzz' if you are not in good posture for the duration of delay)

The buzzing was not too loud to be disruptive in most social places

Also, the buzzing is quite loud and noticeable in an office environment - and due to some glitch within the app, you have to turn the vibrations off several times a day for it to stop freakin' buzzing

The buzzing can be annoying in an office environment

It's very light but the buzz can be great, so it's a good reminder

Walking I very rarely have an issue of being start, but when sitting and you start slouching the gentle buzz reminds me to adjust the posture.

;-)As it is at the end of the day my daughter is correcting my posture because I’m not hearing the buzz!Continue to recommend it!When asked what the little square is I answer that it is

It reminds you with a gentle vibration and a buzz

This is a simple little device that will give you a buzz if you deviate from a position that you set by pressing a button to calibrate the device.

The buzzing of the sensor is way too loud.

I feel better because I naturally seek an upright, non-slouched position, and rarely need the gentle buzz of the device to remind to pull my shoulders back

I find the buzzing to be quite annoying mostly because it can be inaccurate half the time

So then the buzzing get so annoying that I reset the Lumo to however I happen to be sitting at that point in time - which could be very out of posture.

Gives a gentle buzz to remind me to sit up strait, or walk with proper posture.
