Not sure why? Is this the best of the bunch?** A: Not sure if this one is the best of the bunch but it worked good enough to tighten up the arms of our recliners without tearing the entire chair apart. Good price and worked for me. **Q: What is the length of the 3/8" extension? Thank you.** A: the 3/8 one is 8" end to end and the 1/4" one is 6" end to end. They seem well made but like any flexible extension I think if your trying to free a very stuck bolt you might break it. Although the few times I've used them they have worked perfectly. **Q: Do these have the logo engraved on them?** A: The logo is not engraved ## Customer Reviews ### ⭐⭐⭐⭐⭐ Parfait pour les noix mal situé *by F***B on 22 May 2026* Ça sauve la vie ce petit bidule ### ⭐⭐⭐⭐⭐ Da para usar até proficinalmente *by R***E on 8 November 2025* Muito bom e atende as expectativas até para usuários profissionais ### ⭐⭐⭐⭐⭐ worked great getting plugs out of a Yamaha R6 *by S***E on 6 July 2018* worked great getting plugs out of a Yamaha R6.
