What household item do you wish there was a trial/testing period for? (lemmy.ml)

I know some companies offer 90-day returns etc, but what item would you think everyone would benefit from if it was an industry standard to have a test drive like new cars?

My nitpick would be microwaves. I have tried picking out what I thought was decent microwaves in the past but it's hard to know exactly how it functions without using it. For instance, my microwave has an express button (30 seconds) or a minute plus button. You can only use one of them, if you've hit the minute button the express button doesn't let you add 30 seconds while it's active and vice versa. Also the beeping, even if you hit the stop button and open the door when it gets to 0 seconds, it still goes through it's "I'm done" beeping which is loud and repetitive making you stop it at 1 second and still having to click cancel which makes noise. So what's your choice?

You should look into variable speed compressors and the temps at which refrigerants work. You’re correct on many points but misinformed on others.

I know about inverter compressors, but they cannot defy the laws of thermo dynamics no matter how fast of slow they run. It's impossible. If it's too hot outside, the heat will not escape the condenser and will go right back inside rendering it useless and not cooling.

You will only see benefit with the inverter because it can slow down when it's not hot. If the compressor reaches 45degrees, and it's 40 degrees outside with the condenser in direct sun, you can't extracting much heat meaning it'll take forever to cool.

Refrigerant temps will make a difference, but they still have their limits too. All depends on what's being used. I assume OP was sold R410, low chance they were given the newer r32 or r454b replacements.

You’re just flatly wrong, the spec page for the humdrum mini split I pulled up first has a max outdoor max ambient operating temp of 52.78c (127f)

My point in bringing up refrigerant temps was to get you to look into it. Heat exchangers are more effective than you believe. No one is trying to convince you that these units defy the laws of physics.
