If you believe "reviews" like:
https://www.bestreviews.guide/trolling-motors
That put them as Waayyy... better than the top brands which are ranked at the bottom? But, hold on, their SCORE of 9.7 links to Amazon which has...
"Be the first to review this item"
Where did the 9.7 come from, the author of the "review" ?
Also Ebay (or anywhere else) where there is not one single review of them... kinda makes no sense at all.
But, hang on once more... the MK Endura C2 has 1,314 real reviews with score of 4.5 of a possible 5 stars?
At any rate, I'm one of the Amazon reviewers (5 stars) of the C2 50lb and I paid about $60 more (on sale at Pro Bass Shops) than the "Trophy Strike".
So, if by necessity you're value conscious, and if you're tooling around a small lake within easy walking distance should it fail, then it's worth the risk, but since a TM is going to be your only source of propulsion and if you plan on going further than you care to walk, the unknown motor is not worth saving $60 or so.
