[EX Q]: Normally I buy thistle from Walmart but they were out of stock for a few weeks so I ordered this product. I use socks and finches in my yard typically devour thistle like crazy until I bought this product. Cleaned socks and refilled and also tried using in a flat bird feeder and they still would not eat it. Once Walmart obtained inventory I bought it, dumped the Pennington seed and replaced with Walmart product. Birds are again happy feeders Pennington seed now in garbage.
[EX A]: negative

[EX Q]: Well this stuff was crumbly and would not stick to itself. It was like wat sand. I couldn't knead it or work with it at all. Added water and pushed it in the mold and it cracked in thousands of pieces. Worthless stuff don't buy it.
[EX A]: negative

[EX Q]: These put off a lot of heat in kitchen in which you don't want. Heats the kitchen up and in Arizona with plus 110 degree temperatures and increase of an electric bill these are not adequate for your needs. Need ones that don't give off heat.
[EX A]:
negative
