Pros:　
Works well. Very handy. Used it to look into race car cylinders to find bits of metal imbeded in piston. Also found signs of blown head gasket in another car. Paid for istself already!

Cons:　
Extras while good, are not able to be secured to scope very well (I didn't know they came with the scope so were a bonus)

Pros:　
Plug and play. Clear picture. Came with a driver disc, but it was not needed. Just pluged in, waited a few seconds and started up.

Cons:　
Have not wrked out how to use the mirror attachment successfully yet, but otherwaise great tool
