I've been practicing this ever since I bought my first HW around 2017 (if I'm not mistaken), and it continues today. Someone may not agree that it makes sense to buy HW that costs $200+ and have more than one device, but the only thing is how much someone understands that it is actually a small investment compared to the risk they could be exposed to if the only HW they have breaks down.

For us in the EU, the approximate delivery time is 3-5 business days, but you should always consider that the device may be out of stock or the supply chain may be disrupted. It should also be added that with all these regulations that we see every day, we may end up in a situation where HW will not be able to be purchased just like that.
