Im a beginner and decided to buy ctk3500 after reading various product reviews.. i suggest everyone to buy musical products in bajaao as it is not only trustworthy but also cheaper when compared to other sites.. ctk 3500 price was 8500 in amazon and 8900 in flipkart but in bajaao it was 7500 rs and i also got extra 375 rs discount due to first purchase voucher....so i got it for 7125 rs and also a free adaptor ! the delivery was on time and safely packed .. im very much satisfied with the product quality !
