First off, this little tool is a beast in disguise. I was skeptical about its size (only 7.5 inches!), but it squeezed into spots my bulky rivet nut tools couldn’t even dream of. Installing M5 rivnuts on my motorcycle frame was a breeze—no more awkward angles or stripped threads.

The trade-off? You’ll need some grip strength. Compressing the handle for larger rivnuts (like 1/4-20) feels like cracking walnuts, but for M4-M6? Pure smoothness. The quick-change heads are genius—swapped from metric to SAE in seconds mid-project.

Biggest gripe: No case. I tossed the adapters and rivnuts into a $5 tackle box, but c’mon Astro—your premium tools deserve better packaging. Still, after setting 30+ rivnuts without a single misfire, I’d buy it again just for how reliably it performs in cramped spaces.

Pro tip: Keep your Marson tool for heavy-duty jobs. This one’s the specialist you call when space is tight and precision matters.
