That flat hotplate is not ideal for a RBF (Round Bottom Flask.) To use it more effectively, you might try getting a pot the size of the burner, or a bit larger, and filling it with sand. The sand gets hot and heats the flask relatively evenly around the bottom.
When your finances permit, look for a good heating mantle, preferably with stirring. Something like this: https://www.amazon.ca/Heating-Magnetic-HMS1000ml-Temperature-100-240V/dp/B07Z5KTW6P/ref=sr_1_27?keywords=heating+mantle&qid=1574245664&s=industrial&sr=1-27
Of course, then you will need stir bars, if you want to stir your reaction while heating. (You usually want this.) https://www.amazon.ca/Magnetic-Stirrer-Mixer-Diameter-Length/dp/B07461T2PR/ref=sr_1_1?keywords=stir+bar+olive&qid=1574245874&s=industrial&sr=1-1
And it would be good to use a jack to be able to raise the mantle to the flask, so you can lower it when you want to remove heat, and not have to move the glassware. Handling hot glassware is not a great thing to do for a variety of reasons.
The plate doesn't vibrate - you put a stir bar in the beaker, and it is spun around magnetically, like this.
In fact, some kind of magnetic system like this would seem to be a far better way of doing this than the original mug - the motor/battery could be in a removable base, so the top part could be put in the dishwasher. Hrrrmmm..
