My initial bias is using units people I know own. They always seemed to be yucky to use if anything beyond just straight signal was the purpose. They worked. They were cheap. I didn't like using them.
There also was the period of unreliability again from people I know who used their gear. I believe the move to generally SMD construction helped their reliability problems. I don't hear of them just not working like used to be the case.
So while they'll do the job, they are not my first choice. It seems if you step up just one rung higher you'll be much happier with another brand.
For home use, once set up they just keep doing the job. The next step up is somewhat more pricey. Pro gear has moved along somewhat since the 2496 series was introduced but bang-for-buck, Behringer offers a lot to non Pro users.
