I have had the Le Pan 2 for 6 months and it has no problems. However when I got the adapter from Amazon (thankfully it was a bulk like price) it didn't work.
I then found out I had the old firmware or such rubbish that it basically didn't have the HDMI module in the first place. Now to exchange my tablet I have to pay to ship to California. Seems Le Pan stopped providing free shipping both ways around July last year. Too many replacements I suppose.
Now that the price of the actual tablet has fallen I decided to buy a new one and hopefully it works with the adapter.
Caveat Emptor! If you can live with the hassle of paid shipping to the states then buy, otherwise take the tablet for everything but it's HDMI function.
