Deck Devil Board Straightener
Good tool for the money
The deck straightener worked well and was shipped quickly. I would change the way the angle and joist clamp attached to the main body of the tool though. It needs to be anchored on both sides of the tool, not just a pin with a hair pin retainer. The pin bends too easily and with repeated use will soon break. I plan on modifying mine to capture the pushing/pulling attachments on both sides of the tool to prevent the pin from bending; I would suggest the manufacturer do the same.

The only other thing, is I would suggest buying two of these as it would make deck installations go much easier.

Could not give a five due to the pin bending--would not last through multiple deck installs.

More power than I usually need
I used the deck devil on probably ten to fifteen decks. On most pressure treated decks I don't really find its power necessary as I usually just angle in a screw or drive a chisel into the joist and pry it. But there's always those ones where you risk damaging the board or anything doing that and the deck devil had no problems with it. Where I really found it more useful for was on TREX and composite decking materials that are much stronger than pressure treated and sometimes come with big crowns that are a pain to straighten out. There were also situations where I could stand it on edge and use it as a sort of clamp or vice.

Worked perfectly
I used it on composite 5/4 and it worked great. Then I tried it with some 2x4s, not even a challenge. I also tried it on 2x6s, and it worked great. I didn't have a board I couldn't straighten, not one! I even put a tremendously bowed 2x6 up there and it straightened it perfect. I made a little extension and tried it with some 2x12s and it still worked great. The only thing I might change is to add a spinner handle to it. I will recommend this tool to all my friends and anybody who will listen. Thank you!
