Much like my Spark 2, my 5 month old Adventurer strap is starting to split. The plastic they use in these watches is crap. I went through 2 straps on the spark 2 in the course of a year and returned it to REI when TomTom didn't have any straps available to replace it. I picked up an Adventurer because of the hinge at the clasp in hopes that would fix the issue, but alas, the new less than 5 month old watch strap is splitting. TomTom doesn't seem to have any replacement straps available to replace under warranty.
