Recommendation Requests

I need a new gaming handheld. Something that is comfortable to hold. And supports streaming! 

I need a decent UPS. Something to keep my PC and Modem/Router online when I loose power.I'd love it if it has some sort of either remote management for notifications, or SSH. Not sure where to begin looking.

My bathroom scale just broke. I want to purchase one that will last a (long, healthy) lifetime. I want it to be durable and look nice, but I don't particularly care about or want fancy bells and whistles like bluetooth. The scale should do it's very simple job and do it well.

I would like to upgrade the storage available in a Synology DS416 4-bay NAS. It is already configured to use for business data storage as well as Time Machine backups. I'm looking for around 18TB of storage with 2-drive redundancy. What would the best hard drives be for this use case?

I'm looking for a good stand alone voice recorder. Something I can plop on the table and record meetings. And also something I can use to take quick voice memos with while I am out in the field.

I need a decent cross compatible game controller. I mostly play PC but also have a PS5. Doesn't have to be a pro model or anything like that.

I'm looking for a decent air purifier. Nothing too fancy, but I don't want a piece of junk. If you know what I mean. I'm willing to go up to 200$ I need something that can help with my allergies. It doesn't have to be big. I just need it for my office at work.

The title says it all. I'm looking for a decent refurbished MacBook that I can get the best bang for my buck for. I will most likely put Linux on it.  

I just got the new Macbook Neo for school. But I need a dock or port dongle thing. It doesn't move much, so something stationary would be better.
