Lenovo - not very good. Last year I purchased a replacement laptop and chose Lenovo as it “appeared” stylish and had good potential.When I started using it, it was sluggish and there was Vantage Performance Boost I had to purchase before it performed as it should. I felt this was an extra charge for it to do what I had paid for. Perhaps it doesn’t perform properly until you pay for this extra.I purchased the Vantage Performance Boost earlier this year for twelve months (about six months ago) and when it scans now, it keeps saying it will fix the faults it has detected if I take out a subscription (which I have already got but it won’t honour). It won’t let me use the subscription I have already paid for.If I don’t get what I have paid for, I shall scrap this device and shall never purchase this brand again.
