as some of you know last year i decided to buy a new bow. after 15 years of shouting a pse i had a hard time of choosing. but i bought a mathews monster xlr8. well i have had some problems with the bow derailing the string. after a cam change it still did it. so i managed to make it threw the season and sent it to mathews. they have had an upgrade for monsters with this similar problem. they changed out both the axles with ones that have e-clips on them for more stability. i also got new limbs installed. my bow had "dry-fired three times, so this was done as a precaution. i have to say that the tech that i talked to via e-mail at mathews was to say the least "awsome". he was very professional and really cared about my satisfaction and getting the problem fixed in a timely matter. they covered all the shipping and insurance cost for the repairs. everything was under warranty. so i have to give Mathews tech and support a huge thumbs up!!! great job. its hard to find customer severice that actualy takes care of the customers needs these days. i have shot my bow today with a little more confidence. still need to fine tune everything back in now. thanks to Dave from Mathews!
