A zip line that's great (and safe) for ALL Ages!

"We have 4 kids whose ages run from 6-13 and what the big ones do, the little ones want in on! When our oldest asked for a zip line for the backyard, it was an immediate NO from us due to safety concerns. But then we heard about Alien Flier and all of its safety features, so we thought we'd give it a shot. All I can say is WOW! We have had kids from 4 to 65 (ha!) on the line and they have all had a BLAST! With the trigger brake and tow rope you can customize the ride for the most conservative rider, but the craziest daredevil can still do his thing! I HIGHLY recommend Alien Flier, it's the absolutely the most safe, smooth and FUN zip line and the only one we'll ever have."

It is a wonderful product and the customer service was great. I placed my order and received it promptly. I had a couple of questions about the best place to set up and customer service answered all my questions, they were very pleasant, friendly and knowledgeable.
