Hi Lyngut,
Congrats on your success with Harrods.
I myself have to side with vinyl on the impression that Harrods software gave me.
Some have to win and some have to lose, I know, but when I played them I felt completely taken to the cleaners. It was the first time with Kismet software for me and I will darn make sure that its the last time too.
I did not play the Valentine promo, but I played them on the match 50 - 50 BSP intro.
I got cleaned out in a hurry. Flat betting 2 pounds per hand, after just about 70 hands I was already down to my deposit level. Frustrated by my feeling of being cheated I went all in and lost.
At one time I was foolish enough to play the Oyster software, Netgaming was the casino, the first one out of the gang I think, and the software was then known, if memory serves, as Elka Systems The Russian Contraption. At least there, on a $200 - $200 USD match, I ended up, flat betting at $5 per hand, cashing in $290.
This is not based, or backed with any math or research, but as far as smelling a rat, or just plain feeling bluntly cheated, imoho they compare. But of course Harrods is polished with a good look, good CSR and on-time payouts.
Regards,
Thatch
