I didn't agree with his knock on the Clever dripper as it's not comparing like for like i.e. comparing a single cup brew between each brewer.
The Clever Dripper is large enough that making a single 250ml cup isn't risky as the water never gets half way up the brewer and you're going to be picking up a mug anyway too so it seemed like a weird point to make. Though perhaps there are accessible mugs/cups out there so my counter point may be off.
Still the hoop looks like a cool brewer but I find brewing with a Clever dripper so hassle free (I do the water then coffee method so no goose neck kettle needed) that I couldn't justify getting it myself. The price is a little too much in my opinion
