I had one several years ago and gave it away, replacing it with a Husky.
Fastway (you gain up to 6" height minus wheel if you had one):
Pro- avoid some blocking under jack, is fairly sturdy on a light weight trailer, simple to use.
Con- you always have to deploy it, even when not needed. It is only 'rated' at 1,400 lbs MAX, wobbles a bit and may not deploy properly (as described by OP when it did not fully 'seat')
I replaced it with a Husky Brut Super Foot. Pull a spring loaded pin to deploy or secure in up position. Gain around 12" (less if you want to shorten it).
Pro- more sturdy, rated at 6500 pounds. You may use extended or folded. I usually put one 2x6 under it and don't extend it (by design, it lays flat on board) If I have to raise tongue quite a bit I extend it without anything under it. You can shorten it by cutting off a bit and drill new holes. Easy install, but read directions. You use one hole for manual jack, the other hole for power jack.
If you get either one be sure and first chock the wheel under load before unhooking the trailer as you should be doing anyway. If you don't and the trailer moves a bit there is obvious stress on the foot (and the jack).
