I purchased a VM8 4 years ago, and it has been nothing but a money pit. I call it the Delorean because it looks great, but is always breaking down. I have had countless experiences with customer service, always getting the same 'your item is no longer under warranty' issue. While it was under warranty, I had to replace 4/5 modules- that's in the first year! Should have known it then. Since then I have replaced the capnography module twice, the ECG module 3 times and the pulse ox 3 times and the blood pressure module once, then I just left it when it broke again. They gave me a 1/2 price deal the first time, then gave me the 'special' price the 2nd time. I'm pretty well resolved to sending it to the junkyard as it's just costing me money.
