I have got one bat myself and I have got a couple for my mates in the past. The bats are nice. The only problem is that they absorb moisture too quickly since the wood is very dry. I suggest buying at least a couple of oz lighter bat than what you need since after oiling, applying a scuff sheet (and it absorbing moisture naturally), it will end up being heavier than it arrives. it is true that a lot of Indian pros (Kohli, Jadeja, Ashwin, Dhoni, Pandeya etc.) use his bats and past pros were also quite fond of their bats.
What has been said about their customer service is true - Harjeet isn't very keen on following up. They sell bulk volumes everyday and they don't have enough time for individual customer. Having said that, the price for which they sell their bats is almost unbeatable for the quality.
