I was such a huge Dyson fan, bought a cleaner a decade ago, read his books. Had the suspicion the cleaner was crap. Lots of reviews said the same. But I convinced myself I and the others were wrong, Dyson is a genius. Some years ago I finally admitted it was expensive crap and got something else.

Of all the dyson products I have (2 vacs, 1 bladeless fan), customer service is the weakest link. The fan has a recall last year, they should have emailed customers shipping labels to print out to drop off the product at our convenience, but rather ask you to visit a local UPS B&M store and the store clerk had to fax the RMA request in. The whole thing took 2 hours on a busy Saturday. Completely failed customer servi…

In the UK at least Customer Service is superb. I honestly cannot rate the company enough.

On the few occasions I've needed anything Dyson simply ask for the serial number and I describe the part. Next day or two and it arrives in the post.

They also do on site visits if the vacuum has any issues. £80 labour and parts inclusive.

I mean my mum still uses her DC02 from 1995 and it works just fine.

They're (in the UK at least) a top, top company.

I have a Koncept Z-bar desk lamp (~$300) that I got at my lighting shop after looking for something that was cool to the touch and had a nice even light pattern. One minute I use it on "low" for lighting up my desk and the next I'm using it at full brightness for computer vision tasks.

I suspect that you have to be old enough that your eyes need a little help before you can appreciate a good lamp.

Is it just me, or does this completely fail to mention the amount of lumens it produces, the wattage of the lamp, or the incandescent-equivalent rating? Basically, all the fundamental parameters you'd normally expect when buying a lamp aren't there.

"Eight LEDs provide 587lx of warm, white light for 37 years" But that's the only reference on the page.

Yeah, which is pretty meaningless because lux is a measure of light intensity at one particular spot and it doesn't provide any information about the distance at which that's measured, how big an area it'll reach that lux value over, or anything. My little 1 watt torch could probably produce ridiculous amounts of lux so long as it was only over an area the size of a postage stamp, for example.

Yeah, it's getting hard to find a fan that I can run at night to cover the noise of the city. Every time I buy a fan, it's quieter and quieter, but I like loud fans to help me sleep.

No sarcasm: Look into Nursery Sleep Soothers. While they sell white noise machines targeted at adults, they're all terrible because it is a niche market. But in the nursery sleep soothers category you can find a bunch of high quality white noise machines for a good price. For example the Marpac Dohm has an actual spinning fan inside designed to generate white noise. But you can find digital noise simulators who can d…

Is the Marpac Dohm actually targeted at nurseries? I've seen it quite frequently in medical waiting rooms. It helps provide privacy for those having sensitive conversations behind flimsy doors.

On Amazon at least they sell it under Baby Sleep Soothers and Sound Therapy Products.

I'm really surprised that there are no technical specifications that would include, say, colour temperature. I've yet to see an LED bulb that produces light anywhere close to the warmth and spectrum spread as a halogen bulb. At $649, I'd definitely need to see that in person. I'd also be in favour of a 37 year payment plan at $17.54/year.

LED bulbs have been getting gradually closer to the color fidelity of incandescents, I would think for most people in most situations, those with a CRI greater than 90 would be sufficient (certainly worth it for the the efficiency gain), e.g. https://en.wikipedia.org/wiki/High_CRI_LED_lighting

I bought one for our baby's room, but when I decided I wanted one for myself, I hit on a much cheaper solution; I just turn my clock radio to an empty station and crank the volume.

> Is this a joke? I see you're new to Dyson's business model. Keep in mind, these are the guys who make a $400 fan in a niche full of $10 competitors.

My mom once got a Dyson vacuum cleaner. I can only assume Dyson pivoted from making a jet engine.

I bought a dyson. To test it, I vacuumed with my old unit, and then immediately vacuumed with my dyson. surprise, I managed to completely fill the canister.

they're noisy and expensive, but they work really well.

I thought heat pipes needed convection to work. How would the liquid move in a straight, level pipe?

There's no liquid involved. They use a copper part, similar to the heat sinks on CPUs.

You are wrong. Look at all the other responses. And https://en.wikipedia.org/wiki/Heat_pipe
