Warped records are a real thorn in the side for collectors—whether it’s poor storage, manufacturing defects, or just bad luck. In this video I review the Pro-Ject Flatten It record flattener to see if it can genuinely fix warped records without risking damage to the grooves or, worse, your cartridge cantilever. I also talk through why the old “two heavy books / two panes of glass” approach is slow and hit-or-miss, and why the oven method is, frankly, a high-risk path I wouldn’t personally go down. I walk through the Flatten It’s build and operation: it’s understated, extremely solid, and supports all record sizes and thicknesses. It’s temperature controlled to a max of 58°C (136°F), and Pro-Ject recommends a first power-on test to ensure it doesn’t exceed 60°C—mine didn’t, so happy days. I ran a normal warp through the recommended 2-hour heat cycle and cooled it down to around 30°C, and the results were properly impressive. Then, for a bit of fun, I deliberately cooked a charity shop record in direct sunlight until it resembled the Rocky Mountains—and the Flatten It still brought it back to a playable, flat result. My verdict: brilliant results and robust build, but it’s expensive (around $1,000 / £750) and fully manual—no app, no automation—so it’s best suited to serious collectors or dealers with the space and budget.
