Never heard of it but let me take a guess. Given the guarantee I would say it is a certain bet that it uses a loss-chasing staking system betting on short priced horses. As has been discussed here many times before you can get 95-98% "winning" days with this type of system with small profits BUT when you lose you lose big time (so a "winning" day might be $10 profit, losing day is $1000 loss).

Giving money back guarantee for 6 days is a joke with this type of system as the probability of a small win on 6 days is pretty high. If you do win the six days then you probably get back $100 out of the $295 you have outlayed (so you are still down a couple of hundred) while the people who sell it are up $295. If you lose in the 6 days then you get your $295 back but have probably lost $1000 or more on the day - the people selling it don't lose a cent.

If it is such a good system ask them to give you a guarantee to pay back any LOSSES incurred in the first year of using the system and see how fast they run!
