One thing about "refurbished" machines is the question "why" are they refurbished. Was it a faulty part, repossessed, damaged/scratched or even returned for no reason, etc.
When repairing a "returned" machine has the hdd, cpu etc. been changed to make it a now working unit (are all the replaced parts new ??). Is my OEM OS now legal as these parts may have been replaced. , Why are they reselling it so cheap ?
All these factors contribute to an extended warranty being a good idea. But one thing that many people may not realise is that these extentended warranties are usually not offered from the manufacturer or by the reseller but often by an outside underwriter like an insurance company which make money on the fact that maybe only 1 out of a 100 claim back within the extended warranty period.
This is why regardless of the product (washing machine, TV, fridge etc.) they give you a warranty price which covers the replacement cost which is usually much less than what you paid for it initially, as they've covered the cost from the other 50+ that don't claim.
Most of these companies rely on the fact that the unit should be fit for purpose and outlast the so said extended period.
I work for a large independent internet electrical reseller (which will remain nameless

) and we use companies like this all the time (as this is the norm in our line of business)
One thing I will say though that is if you have a claim, these so called extented warranty companies will do everything in their power to put the blame on yourself, by claiming that you've opened the unit, changed memory and many other excuses to pass the blame and clear themselves of many claims.
Remember these companies have been around for many years and have very large and expensive legal representation so they will try every trick in the book
Believe me --- been there --- done that ---- and read the book ... just a heads up
