If you have bad kickback then I vote for a timing problem. Yoiu may want to check both the flywheel and the camshaft alignment carefully.

I agree 100% in my experience that most stores and manufacturers don't stand behind their products. But there's also the DIY issue. I'm a DIYer not a floor installer, but I've installed maybe 20 floors of different materials, and about 10 were bamboo, different finishes, flat, vertical and strand, going back about 15 years. Lived in those homes for several years. It does scratch and dent. I don't know what test they do to get that "harder than maple" and I assume the test they invented is true, but that only means for that specific test maple wasn't as hard. In normal application, in my experience, bamboo dents pretty easy. That's marketing. Why anyone would ever trust anything any store or manufacturer says about their product I don't know. That's just not the way our system works or as ever worked. In my experience the more a seller says a product does X the more likely the opposite is true. But that's true for all flooring I've seen and used. I do think natural wood hides scratches and dents really well, can even improve the look if you're into that look. The room I'm sitting in now has blonde bamboo flat grain and black strained bamboo in a pattern. I see lots of scratches and dents in the black and none in the blonde. I'll bet the blonde has just as many, just don't show up. And of course the dirt really shows up on the black. True for all floor material. To me it would be really cool if a manufacturer did this...most problems have to be seen in person to have any hope of determining the problem. So when customers have a problem it would be nice if they sent out a trouble shooter and if the problem is their floor the visit is free and if not the customer pays for the visit. Of course that's never going to happen. I'd like it because it might lower the cost of flooring I buy. A lot of the cost if to cover dealing with floors not installed correctly. I don't know anything about this floor cause I'm not there. But a couple of things stood out. It's not possible for concrete to ever be DRY. Even here in Phoenix, humidity < 10% much of the time, rain a couple of times a year, if we place some plastic on a concrete floor that's in contact with ground we will normally see moisture collect within a day. That's just the way concrete works. Also, I don't know what was glued..."click" flooring shouldn't be glued in my limited experience. I don't know if the jointed were glued or the floor was glued to the concrete. I personally wouldn't glue any flooring to concrete because it's a pain to get up. But also I think glue is a risky vapor barrier. If you really think there was a problem with the flooring and the install was done correctly you can hire a professional floor installer to do an inspection for you. Get the most reputable you can find. Expect to pay a fair amount. Expect them to pull up some flooring. If they agree you have a case. Send a report and photos to the manufacturer and retailer making sure the manufacturer knows you sent this to the retailer. Ask for a specific dollar amount. That should include the cost of material, install cost (even if DIY) and inspection costs (attach receipts). Say you'll go to court unless the claim is paid in say 60 days. Forget about threats about reporting them to BBB, Yelp, and whoever else. They don't care about that stuff. They sell to thousands of customers a year and expect 1%, 2% or whatever to complain. You don't want to go to court, they don't want to go to court. You and they both know no one is actually going to court...probably. But they do know you're not just one of the dozen people that call them a day complaining about stuff and swearing at them. They know you're probably not going away and who knows might even actually sue. This increases your chance of getting a settlement. Timing has a lot to do with whether you get money or not. The person at the other end has a budget for refunds. If they have money left your chances increase. The money comes from other customers in the form of higher prices. The bottomline is they know their product claims are at the outer edge of being true. And you should know you didn't do the install 100% correctly because in the history of the world no floor has ever been installed 100% correctly. It probably isn't even possible. The real question is whether you can get compensation for what believe is a valid claim. And that has little to do with who's right and who isn't. It's a game, its our system. For others not wanting problems I suggest hiring an installer with a guarantee that says they'll fix any problem you want fixed. Expect to pay a lot. The customer is always right as long as they pay.

I have no clue about our duct work, we vent at 90 degrees to exit house, about 8 feet. Our "quiet" 600 CFM sounds like a locomotive when on high, and our smoke detectors always go off when I cook steaks inside. I have the wolf df range, and I also suggest your hood be at least 6" wider than your cooktop so that it works on your outside burners. Working within the confines of HOA will probably determine your appliance choices. At least you have some existing hood/duct work, rather than a recirculating filter system. Huge plus!

I hate to say this but you contracted with a developer not a custom builder with an architect to represent your interests. I've run across far worse stories than yours. In any endeavor where additional risks are accepted in order to reduce costs it is wise to carry a contingency in the budget to correct the inevitable deficiencies. Homes are unique and therefore the more homes a developer constructs, the more deficiencies. If they fixed them all they would go out of business.
