We have had both manual and electric. The EAGLE came with electric which we thought would be nice. They are easy to extend and retract, but the issue comes in with actually stabilizing the EAGLE on the electric units. The manual ones were ROCK SOLID and there was NO movement in the TT. The electric ones there is still movement after they are lowered into place. There is a little LESS movement if I put about 6 plastic spacers under each one. The only time that the EAGLE is motionless (DW is happy) is when there are concrete blocks (16x8x8) under each leg. The next TT will have the old fashioned manual units. Until then, I will be investing in ear plugs.
Just my thoughts,
