I m Carry, the owner and current Author of projectors place. I used to watch all the new series, play games, and watch movies on my television for so many years. But one day, my friends told me about replacing tv with projectors.

At that moment, I thought, why should I restrict myself to a smaller screen when an alternate option like a projector is available on the market.

So, I began searching the internet for the best projectors in 2014. And to be honest, I didn't find the information I was looking for.

But then, on my friend's suggestion, I purchased a BenQ 1080p projector in 2015. After that, my love and interest in Projector started, and I kept reviewing the latest available projectors available in the market.

I wrote down each advantage and disadvantage of the current Projector model. I gave only an honest reviews to my readers on projectorsplace.com and my social media pages like Facebook, Twitter, Pinterest, Instagram, etc.

If you feel I have left any projector model uncovered, let me know on my official email id: [email protected]
