I am finding success with kratom bird after having GW and MaxR from kraatje and being very unimpressed. Shipping fees are similar I believe but the product is much cheaper, and definitely real kratom. The last stuff I had from kraat made me wonder. The ones on sale are the only ones I know are good for sure, I have more samples on the way, though. Red is my favourite of the Kasung strain on sale. Found yellow to be a bit too mellow. Green definitely works, just depends what you want to get out
