Q: Too many bad grammar reviews point to bogus reviews using english translation programs. Is anyone else concerned?

No not concerned at all. Even name brand American product advertisers embellish and some even lie so it doesn't matter if the English or grammar is "bad" in the review. The reviews in perfect English could also be a lie. You take your chances with whatever you buy. If the product is not satisfactory you can always return. Just contact the seller.
