My LM-2 was problem ridden from the day i got it. It had so many issues i can't even remember them all. Constant firmware fixes came out, some worked, some didn't. I bought mine during the time the company changed hands. Phone tech support was worthless at best IMO. I tried to get them to replace the unit after 6 months of not being able to get it working properly and was told it was out of warranty, even though all of the problems were reported during the warranty time frame. It now sits in its case high on a shelf as a reminder to never buy another IM product for as long as I live. Way too many glitches as far as I'm concerned. When i need a tool of any kind i don't expect to have to have to waste time to fix it before i can use it.
It seems to me they rushed this product to market and did little to no field testing prior to its release. I don't like being the guinea pig for their R&D.
