This unit protects my desktop computer and printer. I experience one instance that it did just that. Instead of my computer and printer being zapped by what appeared to be an electric spike, the Tripp Lite tripped the room circuit breaker rather than damaging my PC and printer. Since the computer and printer stayed on I didn't lose any data nor have any damage done to them. The only negative would be that it's not easily moved because of the weight and does take up more room than a smaller less powerful unit. A small price to pay for a good product.
Had issues using google iprojection for PC. I was not able to get this to work. Overall the product could be better. I tried Multicast but it's not available for the model projector I have. Overall, I was able to use my mobile device to view images.
