"Very weak coffee, but good for tea" star star star_border star_border star_border I really liked the concept of this device, and I used it for a few days, experimenting with stirring it more and leaving it in for up to 15 minutes - but it just makes a very weak cup of coffee, and it wasn’t for me, so I returned. I think this could be great for tea, but there are other methods to make a good cup of coffee which make a better cup of coffee. On the plus side, no issues returning in store. Ms McLean - 10 June 2021 support_agent A note from the team We would ould suggest for a stronger cup of coffee stir and twist the stick in the mug to release more coffee after brewing for 4 minutes or longer. However we’re very sorry to hear it wasn't suitable for you, but glad to hear you've already been refunded.
