Lewis Law sounds like a one-man ambulance-chasing bottom-feeder. His web site consists of an "under construction" page.
Why would a *reputable* law firm make a press release that they are merely looking into something - i.e. conducting an investigation? The only answer is to fabricate a case, then troll for "victims" to be plaintiffs.
And so-called the press release clearly states that it is an advertisement.
I truly hope that no Tunze pump owners contact this scumbag...
