The Bondhus long L wrench is a fantastic addition to any industrial or scientific toolbox. Using this product our team found that it provided excellent leverage and grip, making it easy to remove and tighten bolts in tight spaces .The extra length was especially helpful for reaching deep into machines without having to contort our arms. The only downside we found was that the largest size available is 17mm, limiting its versatility for larger jobs. Overall, this product surpassed our expectations and we highly recommend it..
