Overall, a great value. One concern is that we had two magnets purchased pull tested by third party. Magnets advertise a 2.5 safety factor, which would have a breakaway point of 2200lbs. One of the units tested achieved 1900lbs, the other was 1700lbs. Not a huge concern, as they both tested well above pulling capacity, but we will monitor as they are re-tested every year. Only other concern is lack of spare parts availability. We use magnets on daily basis, so components need to be replaced periodically.
