LAB makes good putters. What failed was the golfers would think the equipment is the solution to their putting issues.
I would suggest after put in a good faith of practice and some guidance from a second pair of eyes, the next logical step is to have your vision assessed.
I've only said this because one can only aim at what one thinks he is aiming. If the alignment is off, then everything else will follow.
After I got diagnosed with my vision tendency, I can use any style of putter, just a matter of whether I like the look at address. Unless the putter is off beat with weight or offset angle.
