⭐⭐⭐⭐⭐ James Peterson - DIY Enthusiast
"I bought the STR Mini Homework in February 2025 for my garage workshop, and after 5 months of regular use, I’m thoroughly impressed. The water-cooling system makes a huge difference—no more overheating blades or burnt edges. As someone who works with TCT blades weekly, this machine has extended their life significantly. The angle adjustments are precise, and the digital display takes the guesswork out of setup. For a hobbyist like me, it’s professional-grade performance at a reasonable price."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Elena Martinez - Cabinet Maker
"As a full-time woodworker, blade sharpness is non-negotiable. I upgraded to the Advanced Model in October 2024, and after 7 months of daily use, it’s been a game-changer. The motorized angle control (±1°) ensures every blade is sharpened to exact specs, which translates to cleaner cuts and less sanding. The 350mm max diameter covers all my tools, and the 20% faster cooling keeps the machine running during back-to-back sharpening. Setup was intuitive, and the safety switch gives peace of mind when training new apprentices."Purchase Date: October 2024 | Usage Period: 7 months
⭐⭐⭐⭐☆ David Lin - Construction Foreman
"We use this on job sites across the state, and the portability is a major win. Purchased the Base Model in January 2025, and after 6 months of field use, it’s held up well despite rough handling. The 15kg weight and foldable design let us toss it in the truck without hassle. It’s not the fastest under heavy load, and you do need to refill the water tank every few blades, but overall, it keeps our circular saws cutting cleanly. For crews working remotely, this beats hauling blades back to the shop."Purchase Date: January 2025 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Thomas Reed - Facility Maintenance Supervisor
"We operate a large woodworking facility and tested three sharpeners before choosing the Pro Model in April 2024. Now, 8 months in, it’s clear we made the right call. The IP54 rating is crucial in our dusty environment—no issues with clogging or electrical faults. The 0.5° precision adjustment and 450mm blade capacity handle our industrial cutters with ease. Combined with the 30% faster cooling, we’ve reduced blade downtime by nearly half. It’s a premium investment, but the ROI in blade longevity and productivity is undeniable."Purchase Date: April 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ Sophie Nguyen - First-Time Buyer
"I was nervous about sharpening my own blades, but the STR Mini Homework made it surprisingly easy. Got the Base Model in December 2024 and have been using it for 4 months. The motorized rotation does most of the work, and the LCD angle indicator helps me get consistent results. I love that it’s compact—fits perfectly on my workbench. Only learning curve was managing the water flow, but once I figured it out, sharpening became routine. Great tool for beginners who want pro results."Purchase Date: December 2024 | Usage Period: 4 months
