What's the most expensive thing you've come to own that you've never gotten to fully use?

I got a pretty nice Yamaha bluray player that was an appropriate match to my home theatre amp.

Put a bluray in it, got a piracy warning, a few unskippable ads for other movies, an obnoxious excessively drawn out animated menu screen that stuttered like hell and was laggy to use.

Pulled the bluray back out of it, stuck it back in the DVD drawer and proceeded to download a copy of the movie to watch. Been doing that ever since.

First edition, first run of the three Lord of the Rings books.

I can’t bring myself to open them up and mess with the pages.

A pool. It came with the house, but damn is it expensive to maintain. I say I've never gotten full use out of it because I spend way more time and energy maintaining it, than I do using it.

I have a college degree I have never used. It wasn't cheap even tho much of it was paid with grants.

Probably 500+ bottles of expensive wine, more possibly even. Some of it was free, but most not, and it's all crammed into a 2 bedroom apartment turning to vinegar because it's improperly stored. Sometimes life circumstances mean you can't drink much anymore. So it's pretty much a waste and hugely embarrassing.

Never tie your finances to that of a crazy liar.

Speaking on my wife's behalf, an epipen. We're both content with not having needed to use it.

My Switch. Just lost interest after playing a few games

My house. There has never been a point in time where there was not at least one room unusable due to ongoing renovation.

Bought a brand new truck for my in-laws. Only brand new vehicle I've ever bought in my life. I get to drive it for a month every couple of years.

My mixing studio monitors, I haven't properly gotten into mixing yet.

My Les Paul. I go in fits and spurts with learning to play the guitar, and haven't gotten around to figuring out the effects of all combinations of the volume & control knobs.

Back in December I spent $550 on a refurbrished home theater projector. After actually thinking things through, I realized that in my current living situation, the whole idea isn't going to work. I went back to watching movies on my TV and sometimes even my monitor.

I still haven't taken the projector out of the plastic wrapping, and I've been contemplating re-selling it on eBay so I can at least get my money back...but I highly doubt that will happen.

I bought some kit for running TTRPGs just before COVID hit: wet erase markers, Chessex mat, extra dice bags, DM screen, and some cheap minis. Then when COVID hit I adopted a Virtual tabletop (Foundry). Over the course of the pandemic, my gaming group evolved to include people from all over the province, and so now there's not really any hope of playing an in-person session. Not to mention I switched to playing PF2E, which is really hard to run in-person because of how much crunchier it is. So now I have this stuff and don't really know when I will get to use it.

My car's extended warranty.

I suppose the anti cat gate. Got it because new kitten wasn't getting along with adult cat. Kitten continued to not get along despite doing everything and asking the vet for more advice.

Kitten is with my mother and her cats and he gets along with both of them.

The anti cat gate stands there, expensively.

Akai EWI Solo

My partner insisted on getting me one of these as a gift because I like playing music. It's cool for sure, and I enjoyed the little bit I've played on it, but there's just no time. So it's left to gather dust now.

I've just built a $1200 PC and I'm pretty sure I don't really use the fraction of its power.

My 6-foot-tall telescope. I should really pull it out more, I just get so busy.

A pair of traditional leather boots that were stiff and sturdy enough to support me through anything and last long enough to be buy it for life. The pair weighed over 5 pounds. After 6 months they still hurt after a hike and I gave up breaking them in. Cost me over 300€, and I replaced them with a pair of 80€ trail running shoes which were better in every way for my use case and also lasted 12 years.

I bought an $800 half stack guitar amplifier in 2009 and rarely play with the volume above 1, let alone play shows with it. But it looks neat.

2020 Shelby Mustang GT350R. I paid $80k for it and then another $25k at Shelby American in Vegas for the signature edition package. Bought it new in 2020 and it now has about 1500 miles on it.

It was my dream car but I just never have the time to drive it.

90% of people here would have to say "my car".

Xbox Series X. I have a Day 1 release, and recently cancelled my XBL Gold + Game Pass due to lack of use.

A Fender Telecaster. I love it, but my health isn't good enough to let me play on it very much. Plus, I sometimes wonder if I should've gone for a lighter guitar...

My camera (Nikon Z6) has a lot of features I never use and probably never will. Bit it's still an amazing camera that I can use to take photos with that I couldn't with other Nikon cameras I could afford. So it doesn't matter if it has a weird feature I don't use when I regularly make use of a feature it does so well. Paired with an old 70-200 2.8 I have taken a lot of photos I would have previously not have dreamed possible with my older camera setups.

An ecoflow battery generator. Granted, it's a small-ish one but I got this itch to purchase one after seeing one in action while car camping ("I can use my hot water kettle while camping, how cool!") and when our city was warning us about widespread power outages from an upcoming winter storm ("to keep our devices powered up").

Ive gotten a sub woofer probably at ~$120 of value and a couple pool sticks (billiards) at ~$200-300 value of which I've never gotten to fully utilize yet

Fully use? Synthesizers. I just don't think that's possible.

Otherwise, I'm pretty good about using the things I buy. Maybe my HOTAS and Race Wheel, as those are the most niche gaming things I have. But price/per use is still not that bad, I put a lot of time into some of those games, I'm just not actively playing them as much anymore.

A Honda 2200 generator.

It would be the Nektar G49. I wish I had the time to use it, but I'm mentally tired, unemployed and the rubber from the knobs have degraded to a sticky mess. And I am also an idiot to buy it, thinking that I would get the experience of a full-size electric piano/synth.

And also money and all the other people pursuing similar dreams but who are better looking and richer and more talented than me too.
