The reason some folks have problems is whom they buy from. Where all of these are made in China, The manufacturer of Wilton brands spatula is required to make the silicone spatula and handle to a certain standard, while it seems all the other manufacturers make a cheapo version with cheaper standards. They're all sold here under the branding of Wilton, when in actuality they are not Wiltons brand or Wilton's standards for manufacturing.
Make sure you buy from an Amazon seller that clearly states they are an Approved Wilton reseller and buy their product directly from Wilton here in the United States. You'll pay a couple of dollars more, but truely well worth it! :)
