Every music teacher knows the old story: the student that begins practicing his instrument without a metronome. After a while, he/she can't keep the same tempo, feel the subdivision, and even worse.. make mistakes without being aware of them. Also, a student without metronome can't practice the usual step by step increase/decrease exercises.
Excuses are more than many, but the most common is... it is too expensive! I understand that the financial situation of some families is not the best, so I did a search and found a metronome for as little as 3€ and 60 cents (free shipping).
A simple eBay search revealed some low-cost options, but you should select the Free Shipping and Buy Now options to avoid surprises.
I made a video to show the features...
I wish you a nice practicing session and now, since there are no more excuses...
ALWAYS WITH A METRONOME
