Who The Fuck is S-Fixx? I am writing to express my extreme dissatisfaction with the APX4 Ultra Strength Adhesive & Reinforcing Filling Powders, which I purchased for £9.99 (Inc. VAT). Despite the grand claims in your product description about its “ultra-fast curing” and “powerful and durable bond,” my experience has been nothing short of disappointing and frustrating.

First and foremost, the so-called “fast-bonding adhesive” with a curing time of 7 seconds did not even remotely perform as promised. I followed all application instructions precisely, yet the bond was weak and broke apart almost immediately after drying. This result was not due to misuse or improper application—I even repeated the process multiple times with various materials mentioned in your description, such as plastic and metal, and each attempt failed miserably.

The “versatile” Filling Powders were equally unimpressive. Instead of seamlessly filling gaps and creating a strong, reinforced bond as advertised, they merely created a crumbly, flaky mess that failed to hold up under the slightest pressure. The result was far from the smooth, professional finish your product promised. To call this product a reliable solution is misleading at best and blatantly false at worst.

The claim that APX4 can be sanded, drilled, filed, or painted is laughable, as it barely holds long enough to make it to that stage. Your product has not only wasted my time and money but has also set back my repair project by several days as I now have to seek a genuine adhesive that actually works.

Adding to my frustration, it has become clear that APX4 (marketed under the Sfixx brand) is nothing more than a bad, two-bit copy of Supa-Fix. Who even is behind Sfixx? This product pales in comparison to its superior counterpart, Supa-Fix, which actually delivers on its promises. The blatant attempt to mimic a reputable product while failing so spectacularly is beyond disappointing.

I demand a full refund for this sham of a product and expect prompt action to address this issue. Failing this, I will not hesitate to share my experience with potential buyers to warn them of the inaccuracies in your product’s description and the clear inferiority of Sfixx as a knockoff.
