Acer Aspire ES1-521 Notebook is a cool laptop with good size screen. Its price is suitable for low budget. The quality is good but not best. Durability is not so good as it has only 1 year warranty. Some of the cool features are Optical Drive:DVD-Super Multi double-layer drive, M-DISC Ready, Base Clock Speed(in GHz):1.8, RAM 4 GB, Hard Disk Capacity 1 TB, H.D LED-backlight LCD, Webcam 0.3 MP(VGA), Two built-in stereo speakers, Ethernet(RJ45 LAN Port) Up to 100 Mbps. Some of the disadvantages of this laptop is the images represent actual product though color of the image and product may slightly differ, only Onsite Warranty, Battery Backup Upto 4 hours only, No Dedicated Graphics Capacity, SSD Capacity Not Applicable, eMMC Capacity Not Applicable, Instruction Set 32 bit. Its value for money of people who will use this very less and just for minimal use. Service and support is really poor because it only has 1 yr warranty and that too only onsite warranty. I will not recommend this product because its battery and warranty option is very poor.
