I just have to say what a GREAT company this is to deal with. Last week i was shooting my bow to get ready for the upcoming season and one of tracers quit working.[:@] So i called them up told them what was going on. The lady said that sometimes the battery and circutboard sometimes seperate and that i should wiggle the battery i told her i tried that so she got my name and address said they would mail me replacements ASAP!! That was on Friday and here it is Wednsday the following week and when i get home package at my door AWESOME!!!!!
