I have the Presenter 2 days after the order received (Shipping from DE to NL). Device was used as indicated with damaged packaging. Just a mini-corner to the package canceled. All functions of the presenter function properly, a casing was mitgeliert. About the robustness of course can not say anything yet. However, I am very satisfied, EIA is 50EUR (status August 2014), I bought it for 30EUR (Aug 2014). The only complaint I have the supplied batteries. They are going from Duracell, known for good quality, but given with production date 08/2012. However, as was a strip between the contacts so that they are not discharged in between. All in all: Very good first impression! And quality costs just;) Honestly, when an important presentation no loud click or an unreliable pointer can use. Invested by n few euros more and have it s reliable part!
