I searched team-bhp for reviews and found many good or okayish reviews of TPH but..
1) they are too damn expensive
2) there is not a precise distinction between their covers. For eg on amazon, I found Hamster, Astrolite, Armor within my budget. But when I read the product details, each of them had similar features and couldn't understand the advantage of one model over another. Adding to this, iirc Armor wasn't even mentioned on their site at that time - an year back (now they are).
3) so I WhatsApp-ed them on contact numbers - one I found on their site and another I found on team-bhp. I sent them a msg enquiring about the exact feature set and check if I could get it cheaper from them directly. Then, I didn't get a reply for 3-4 months on both the numbers. And in reply, they sent me the same pics which are already available on Amazon and didn't care to describe the feature set in detail and just said that these are the best car covers and just buy any.
I didn't like the atitude and found the customer service part too lacking. If they can't reply to a sales enquiry, I don't expect them to cater to me after I have bought their product at all.
4) Though they may use better materials in the covers but its not like their car covers are the next best thing since sliced bread either. Team-bhp has a few bad reviews about their covers as well so they aren't exactly fill it, shut it and forget it kind of deal exactly.
So I rejected them and bought a Polco cover - https://www.amazon.in/dp/B099PV6G8C/
Seems to have performed well in last 5-6 months. Was 100% waterproof before someone made a few holes in it while firing crackers at diwali near my car. Good looking too and 100x better than the cover I bought from local dealership for same price. Polco also sells a Tyvek variant, team-bhp recommends Tyvek but I have no idea what that material is so can't comment.
