I bought my carnival clubhouse from Houston dealer of Rainbow play system on Sam Houston tollway. I found this company and its dealer in Houston dishonest in dealing with their customer's warranty request. They would use a number of excuses to deny the "lifetime warranty" - they tried "act of God", when that can't be proved, they switch to "Customer's neglect". You see that you have to seal the wood "regularly" and clean it "regularly" to qualify. Even if you did that, they may still deny warranty for neglect because you didn't do it "often enough" for your "local weather condition". Their dealer will tell you that Rainbow play set cost much more than other similar products because rainbow's wood part are factory sealed and has lifetime warranty against wood rot and even insect damage. But that's just a bunch of lies. The rainbow's wood parts suffers weather damage easily in Houston's weather even though I sealed them every 2 years and kept them free of mildews. Rainbow's warranty lady in S. Dakota said that "it should be sealed every 12 months". If You did that, what's keeping her from changing it to "every 6 months "? The customers can't win in that game.
If you don't want to be ripped off, don't buy Rainbow play systems. You can buy a similar play set at SAMs club or Costco or big box stores for 1/4 of the price or less. That means you can afford to throw away a set every 3-4 years and get a new one for the same price of a rainbow set until you kids out grow it.

Yep, Here in Olathe, KS we bought one for about 4 grand brand new. It was great at first but then the yellow plastic covered rails became all gunky and sticky. NOTHING could clean them. It was like pulling teeth to get those pieces replaced. We had to send pictures, have people come out, etc... It was quite the run around. They finally reluctantly replaced my parts, BUT I HAD TO do the installation. The plastic add ons like the parascope and binoculars lasted about 2 years and the sun just destroyed them. The tarp just got ripped up in a wind storm 2 weeks ago. I knew the tarp would be out of warranty so I called to price a new one. 240 bucks!!! WTF rainbow? Really? Thats robbery. Went to Lowes and bought supplies to make it a wood roof for 110 bucks.
In hind sight I would not buy another. Its better then the ones you get at Sams or Costco but NOT 3 grand better. It would not be bad IF THEY HONORED their warrenty. However these seem to be franchises and most individual owners are really stingy with what they will do for you despite the "lifetime Warranty".
