Wondering the same thing! Maybe I can bump the thread and we can get some take.

My neighbor has cali bamdeck and she absolutely loves it. It does look beautiful and I've never heard her complain about off-gassing or anything like that.

I have been installing Trex since it hit the market and never heard anyone mention that it smells.

As Bamboo decking goes, I haven't heard anything about the brand you mentioned but I heard good things about Moso Bamboo X-Treme decking.

I have had Cali Bamboo decking for 1.5 years now. No smell at all. However, I wouldn’t recommend it for any areas that are continually soaked. It’s ability to retain water and expand / contract are giving real problems. Some boards are splitting, others are buckling and warping. Cali said it’s installer’s issue. The said it is documented in their manual to leave a 1/2” of space between boards if boards are to be in high moisture area. Its not! Neither on their web site! But 1/2 “ space isn’t enough. I’ve replaced their deck material on my dock. Will never use again.
