Got the Dyson v10 just now, and its perfect! It has somesthing in the brush, which keeps the Cat Hair from tangeling up and it really works great, not a single Hair there! Not even one. We had a Miele before, spend 800 € on it and its complete trash. No power, loud, bad haptics, short runtime, and the brush is full of hair after 5 Minutes, it was unusable. We spend 270€ on a used dyson on refurbed.de, local german web shop for used things. I seems like dyson has a own program, where they sell used refurbished devices. So the device is from dyson, but used. Very good condition.

Another thing fir me is, they sell every induviual Part of the vacuum seperatly, if something breaky, just buy that part new.

It is a bit loud, but mave that is just our house, the floor resonates 🙈

I bought a new phone every year, until i bought the Oneplus 5, in 2017. Until then, every new Phone had a "wow"-effect, big differeces in speed, camera, ... Right around that time, phones have gotten so good, that i stopped buying new ones, there is no need anymore. You buy a new phone and the camera is 5% better, you wont see that. I now buy new, when the Phone doesnt get Updates. Currently on Fairphone 4, running Lineage OS. Next Phone will probably be a Fairphone again.

U can use it how long you like. There are only some settings, you cant cange (but only in the settings, when you use the old control panel, you can sometimes still change them). Biggest issues for a standard user would probably be no background image and the watermark.

It is a little bit more efficient, because your PCs Power Supply is not very efficient when you dont use much power. By using it more of it, it becomes more efficient, peaking somewhere at 50%. But: we are talking about very little differences here and only for Desktop PCs. When you use a Laptop, you Powersupply is way less powerful, so you use more of it by just using the Laptop. So in that case, i would rather use the charger. To be perfectly honest with you: All that is not realy worth thinking about. Its like opening your Fridge for only 6 Secounds instead of 8. Yes, its saves power, but there are petter ways to do so. Doing only 1 kilometer less with your electric car ist about the same as charging your phone 10 times.
