The Trailer Aid worked fine on my 4900# GVWR 24 foot Koala TT last March 2017. 2nd axle cleared the ground when up on the Trailer Aid.
Hopefully, I'll get the same results with my Jayco Jay Flight 23RB which is 27 feet long.
Both trailers had/has the regular spring suspension. Maybe one day when I'm hitched, I need to test the Trailer Aid on the new trailer.

These work depending on what type of suspension your trailer has. I have the Trailer Aid version and it worked great with the torsion axles on my horse trailer. I now have a Jayco Toy Hauler and tried it at home for a test and it does not work with the leaf spring system on the toy hauler. One tire went up on the Trailer Aid but the other tire was still on the ground. Glad I found this out at home rather than on the side of the road. I carry a 12 ton hydraulic jack. Hope I never need it though.
