Review on Johnson Level Tool 595 Structo by Patrick Reid

Suitable for small projects. I used the line from the trimmer instead of buying something separately. A necessary thing when working with pavers. Gives you guidance on how to tilt properly. Use both on the same side at 2/6 and 4/6 from the string. This will balance and align you on the long side. The derailleur can be easily removed without removing the cord by using notches (not holes).
