Just received it yesterday, Packed very well, shipped and delivered promptly. No issues with the seller.
The product seems OK. Compared to Micromax 2 in 1 Canvas Laptab(LT666), this latptap(LT666W) has windows 10, but does not have free Office 365 subscription. You will need to purchase it. Moreover, LT666w model does not have 3G connectivity. This is a limitation when one wants internet on the go. The processor of LT666W is better 1.8gz.
There is a lag in response. The touch is OK. I think that there are no hardware issues. The keyboard is not good enough for me. Touch-typing is difficult! However, it does the job. Software issues might be a problem. Again, it all depends on the purpose of the purchase. I bought it as an entertainment and educational device for my wife and kids. Unfortunately, the number of windows based free apps are limited. I should have bought an Android device for entertainment!
If your purpose is to carry your data and not the weight, this is sure a good option. However, it does not have 3g connectivity, you may not be able connect to internet. In general this device is not a substitute for your regular laptop or PC. And it is not as entertaining as an android device. It is surely IN BETWEEN! I like it better as a tablet than as a laptop.
Considering the price, I guess it is a good enough buy.
Maybe upon more usage and exploration I will get used to it and appreciate it better. Will update if I find more merits and demerits at a later time.
