I bought this laptop in March 2016 and I never faced any issues with it, except its screen hinges issue. It got replaced for free of cost from Lenovo.
If you talk about performance this laptop is the best in 42k price range. Its battery lasts upto 2.5 hours with ideal usage. I use my laptop for playing heavy games like The Witcher 3, DIRT, etc. Its 2 gb graphics card is enough for these games. Also I use many softwares like Photoshop CC, Lightroom, Sony Vegas Pro without any lagging issue. Its 8 gb RAM is enough fir the daily work and entertainment. Also you can increase the RAM with its additional memory slot. Screen quality is average, because I have seen other laptop with better screen quality.
