Unless you have a very specific need for the data tracking or automation provided by the PicoBrew Zymatic, you will likely see very limited benefit for the cost of this machine over traditional home-brewing equipment.
SousVant Circulating Sous Vide Oven
The SousVant is the best self-contained water bath we've tested. Anova and Nomiku still make better places to start with sous vide, but the SousVant is a fine option if you're ready to dive in.
Dyson v6 Absolute
As usual, Dyson produced a competent product that costs too much. At $600, the Absolute isn't worth the upgrade over the Linx or even over other Dyson sticks.
Dyson AM09 Hot+Cool ( white)
Unless you're the most devoted Dyson loyalist, you'll find much better values if you shop around -- including Dyson's own AM05.
Eades Appliance Technology SousVide Supreme
Eades Appliance Technology's SousVide Supreme performs pretty well, but it's missing features that would make it much easier to use.
Bissell Bolt Ion Cordless Vacuum
The Bissell Bolt Ion is a bad vacuum. It costs a reasonable $180, but it's such an ineffective pain that I wouldn't recommend it at any price point.
Black & Decker 36V Max Lithium Stick Vacuum with ORA Technology
The Black & Decker Lithium Vacuum is mediocre and tedious to use. It needs to be better than that to be worth its $300 price point.
Instant Pot Smart
This capable cooker returned consistently great results, but the so-so Bluetooth and app portion isn't quite worth the inflated price.
Dyson Cinetic Big Ball Animal Allergy
Dyson reinvents the wheel with the Cinetic series, and though the filterless approach works, it doesn't add enough practical convenience to justify the price jump over similarly capable competition.
Nescafe Dolce Gusto Mini Me ( Black)
If you have a hankering for fancy cafe drinks at home, the Nescafe Dolce Gusto Mini Me is worth a look -- just don't expect anything close to real espresso flavor.
