I'm sorry the screws didn't work well for you! If they're tightened with a very clean/new Torx bit with sufficient downward pressure they will last and work well (I've tightened/loosened mine many times) ...but yes, you do need to be careful and intentional in how you handle them.
I've talked to my supplier about the issue and in the future we'll work on improving this aspect.
I'll send you some new screws at no charge.
Thanks again for your business and support! Sam (TAP Owner)
