I bought a Gaggia Coffee manual espresso machine in 2000 when my doctor suggested I reduce my caffeine intake - at the time, decaf from a pot often had an odd taste. That espresso machine lasted until 2015 when service became increasingly expensive and often took weeks.

I am on a well that delivers very hard water causing lime scale buildup in kettles and hard to remove soap scum. I installed a water softener after the lower element in my water heater failed because it was buried in scale.
In 2017, I was given a SodaStream (https://sodastream.ca/) device that injects CO2 from a rechargeable cylinder into water. The injection rate dropped noticeably in the last few weeks, even with a full CO2 cylinder.

I have been using Logitech computer mice for ages: good price, good quality, and they meet my needs. Around 2017, I noticed recurring issues where my computer would record a single mouse clicks as two clicks.

My LG over-the-range microwave failed after 15 years. It showed an F-5 code which is associated with the humidity sensor. I had replaced the humidity sensor in the previous countertop microwave - it worked for several years until it was replaced to increase countertop space.

I picked up the flange and sleeve bushings mentioned in Ability to Repair: the Mower Wheel. The sleeve was easy to insert into the flange bushing using a bench vise. The flange was too wide to fit into a recess in the mower wheel.

The rear wheel on my electric mower fell off. The mower is getting on but otherwise is still in working order - even the batteries take a usable charge. Each of the rear wheels has two ball bearings pressed into a 1.25" hole in the wheel which rolls on a 0.5" shaft. The inner bearing (lower right) was still intact but also failing.
