[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]: Never received item !!! Add-on item missing from delivered package and not discovered after allotted notification time had expired so no recourse as far as a refund. Shop with Amazon almost exclusively and dissappointed to say the least.
[EX A]: negative

[EX Q]: Bought 2; they both died two after opening them. Tried to recharge batteries but screws in the units are so small that no screw driver could loosen them. not worth the effort to even return them.
[EX A]:
negative
