I got this to replace the bottom part of one that had the wings on a spike. Well as the posters say they use the softest metal known to man and they bend and snap. I think that bottom lastest 2 wks. This seems to be a way better alternative. I put a different brand impulse top on it and it sealed better than its original bottom component so that was great. I am super careful to not force it into anything but soft ground. But I am pleased with this for the price and for a sturdier base
