[EX Q]: why am I being asked to review a product I didn't purchase. Need to fix the system or allow me to delete the request.
[EX A]: Negative

[EX Q]: I only used it a couple of times, a tiny bit of water leaked into the battery compartment and now it is rusted and won't turn on.
[EX A]: Negative

[EX Q]: They keep coming untied! If it wasn't for that I would give it 5 stars. The boot is waterproof, it is comfortable, wont give you calluses or corns. But they have hooks for wrapping the laces over at the top that no matter how you try and tie it, they will inevitably become undone! The first time: "umm? maybe I should tie them tighter", The second time: "just a little tighter, Ugh it's cutting my circulation", The third time: "Ok this is ridiculous, let me try tying em different", the unfteenth time: "you m$#%^ stupid $%^ Boot from hell $%^&..." lol I threw the boots into a lake and hiked in my sandals the rest of the way... Never again will I buy boots with hooks for tying...thanks for reading
