Yes, depending on how and where and with what number of people you intend to use it. And whether it has the larger pole sleeves. And/or your willingness to make modifications.
See above comments about best in far north/Arctic/Barren Lands. The Mantis was a disaster on sand. And about facing away from the wind (& lake views). And, mostly, about the usable space inside for more than a couple of people (or one person and two dogs); as a shelter for your family it would be mighty cramped.

One of the Mantis’ subsequent owners used a long webbing strap with several grommets at each end. The ends of that long arch pole could be held in a variety of grommet positions and that simple grommet strap helped speed the set up by restraining the pole in a given arch.
Of the possible modifications mentioned on the 1st page of this thread the webbing strap with grommets was the only one actually implemented. That strap helped hold the very long arched pole at the correct/best arch, and made setting up easier, especially for one person. It was a little awkward having a strap running across the bottom area, worse on uneven ground where it was lifted in places off the dirt, but with some gear set on the webbing strap to hold it flush with the ground it was a functional and simple improvement.
Had I kept the Mantis for use as a one or two person shelter I would have eliminated all of the (too tight) pole sleeve except for a foot or so at each end and sewn on pole clips for easier set up and take down. And probably have made some wind & rain proof door flaps for the front screen.
