Last year I bought a replacement TreasureMax strap for my Alta because I wanted a traditional clasp instead of a Fitbit stylus. It worked well but was showing signs of aging (peeling paint on the clasp, rubber/silicone sensors) so I replaced it with a Wekin. I figured it would be worth trying something else. The silicone is slightly stiffer on this product, the extra strap loop is twice as thick and the strap itself is slightly shorter than on the TreasureMax. If you look at the photo I uploaded, the pattern is similar and both sit about mid-wrist. I'm 6"7", 225 pounds and don't have a very wide wrist so someone with very thick wrists might find this strap too short. I have 4 extra holes on the Wekin and 6 on the Treasure Max. I especially like that the loop for the extra strap is thicker. It seems to grip better and doesn't slip off during the day. Over time, the loop on the TreasureMax harness became somewhat loose and did not always stay in place. Whilst the strap/straps appear a tad thicker in the picture, this is just an enlargement of the photo - they are identical in thickness. I hope this helps someone make an informed decision! :)
