I've had my Viking for about a year now, LOVE it. Having said that, it does have it's downside. When you first get it it's infinitely easier to put on if you do it on a hot, sunny day, and let the top sit outside for 15 or 20 minutes. Window removal/reinstall is very easy. Only thing I don't like is the fact that it due to the nature of the top, you pretty much have either a full top or bikini, it's a pain to take the entire thing off. I took the entire thing off a couple months ago and it's not been back on since, I have the luxury of a garage and if it looks like rain I drive the Exploder. Viking's customer service was second to none, I had one dealing with Thor himself and I could refer many other companies to him on how to do customer service. Unfortunately he sold the rights to the top to Rampage I think and no longer sells them himself. The price has come down quite a bit as a result though. Can't speak for quality with Rampage making them. Would I recommend? Sure, just be aware it's (obviously) a lot different than a factory top where you can have a full top, bikini or topless, with this it's alot more work to go topless.
