Maestro House Mini Coffee Scale
I have begun to drink tea, pu’erh tea to be specific. I have several varieties and I have had a problem with getting consistent results. The varieties can be very different in size depending on when the leaves are harvested (leaves harvested in spring are much smaller). So the easiest way to get consistent results is by weight. This scale is very easy to use with a ceramic tea scoop, set the tea scoop on the scale, zero it out and add tea leaves. This has made my results much better, without the wild swings in strength I had been getting before trying to eyeball even measures. This scale gives me accurate measurements to one tenth of a gram.

Mostly great, except one little annoyance
Color: Black&Silver, Color: Black&Silver
Pros- lightweight, small, very accurate, easy to clean, timer included.
Cons- I use this to brew espresso on my Breville Touch and to get an accurate reading, you have to place something flat (structured) under the scale. Otherwise the reading just jumps all over the place. I know lot of espresso machines have the same base, so this might be an issue for some!
This is my reason for 4/5 stars. It’s an easy fix, it’s just kind of annoying. Value for the price seems to be on point. It’s easy to clean. It has a timer as well as scale (nice for espresso). Buttons work the first time you push them.
That’s it that’s all

Great Coffee at Home with Beautiful Design!
Color: Beige, Color: Beige
Absolutely love this espresso machine! It’s easy to use, heats up quickly, and makes rich, flavorful coffee with nice crema. The milk frother works great for lattes and cappuccinos, and the design looks beautiful on my countertop. Great value for the price — highly recommend!

Great little espresso machine for home
Color: Silver
I purchased this as a test case for home latte making. Considering the price, it is an excellent starter machine. The learning curve is not very dramatic and it is relatively easy to maintain. Unit is attractive and build quality is very good. Be sure to use filtered water. I have been using it regularly for months now and it has proved reliable. This has a very small footprint and would fit on most countertops. If you are looking for a starter espresso maker, this is a great option until you want to get really serious.
