150 feet clear line of sight is not a long distance.
So your suggesting they use one of your several hundred dollar setups when a $35 to $40 single device will work fine? Honestly all you do is come in here and post "use one of our kits". If you're not a forum sponsor and aren't going to contribute anything other than that, would be better to just stay silent. At the very least qualify what the person is looking to do and only spam the thread when your product is actually the right one to use. Considering much more tried and true versions from other companies are cheaper than yours, you're facing an uphill battle.
