Screen guard is nice and working okay for me (I do not have any experience with any other screen guard). When DHD is in sleep mode, you can easily see the finger prints on its screen otherwise 50% of screen brightness is enough to show you nice screen of DHD.
The screen guard is probably a local one (brand name was copper ..) & the mechanic of the shop applied it on DHD in 5-10 minutes. He did use scissors to chop off 2-5% of original screen guard - he did his job nicely. He did say that screen guard which he has applied costs Rs.400 in market but I doubt it.
Why I paid 26.8k

? In Bangalore, I heard of that 2-5 people got DHD in 26k from this shop only. And this shop guy had perfectly realised that he is the only one offering the cheapest DHD in town - I knew it & he revealed this secret on my face

. I had been talking to him for 2-3 days. Moreover, I already have had enquired 4 other shops - New Jagat Associates, Marathahalli - 27k; PDA Cafe Garuda Mall - 27.8k; Sangeetha Mobiles, Forum Mall - 28.2k; Akshar Telecom - 27.8k. No one was willing to lessen even a single paise. I considered 26.8k as best price. And the shop owner gave me screen guard for free - I was convinced.
