The new handsoap my wife switched over to ~6 months ago and the corresponding all purpose spray to clean the counters with. It smells amazing and literally makes me clean the counters more often just because I like the smell.
My ~$10 coffee grinder that I've had for ~10 years. Thing is a tank and the smell of ground coffee beans might be just as important/nice as the coffee itself.
Pilot G-2 pens. My wife and I literally don't buy any other pens. Love how these feel when writing and get very frustrated when force to use inferior alternatives.
Adam's Polishes Leather Conditioner. That stuff smells amazing. When using a foam applicator, a little goes a very long way. Keeps the leather in the car nice and helps car smell fresh.
Our Roku. Between the ability to use an app on my phone as the remote, a button on the device to ping and find the remote, the small profile of the actual device, support for 4K, and the generally easy-to-use nature of the device as well as continually updated/supported apps (unlike every Smart TV I've ever owned)....the Roku is pretty amazing.
My carryon suitcase. It was a cheap gift, but damn this thing is durable. Hundreds of work trips and this carryon suitcase has never let me down.
