I had some of the nauticus plastic smart tabs. They did some good with getting on plane better. The real problem was my prop was too big. The plastic bracket on the boat broke (maybe I hit something). They sent me two new ones b/c of warranty. A while later I noticed the boat was pulling to one side. One of the cylinders had locked up. All of the parts were not stainless and there was some rust at the cylinder ends. I would not recommend these, especially if you ever run in saltwater. On the other hand, I put a set of Bennett hydraulic tabs on my dad's offshore boat. They are still working perfectly after 5+ years. It is a trailered boat that probably gets taken out about 5-6 times a year.
