Review on U-Likee Recordable Button-Dog Buttons- Dog Speech Training Buzzer-Record Any 30S Message with Included Battery (White) by Joseph Hall

I have no problems with this product at all! They work very well and are easy to record and re-record. My only "complaint" (and it's a VERY small one) is that I'd like the button colors to be in shades that dogs can actually tell apart. For example, green and red look the same to dogs, but they CAN distinguish between different shades of blue/purple, yellow, and black/grey/white. I know this is an unfair complaint as to the actual quality of this product. That's great, but I think it's still worth mentioning.
