I regret engaging Eric and Welmax. I misled myself after reading the earlier posts only. I should have read all the post before engaging them. My experience is terrible. Comparing with market rate, their price is slightly cheaper but the work output is worst. I am considering complaining to CASE. Looks like I have to touch up on my own to improve the condition of the grill or live with it. At least, I can complain to CASE.
