Is Samsung Galaxy Ace Style anygood?

Im asking is this anygood in the sense that is 4 inches enough and are those pixels enough to make sense of anything. I have quite an old phone and just would like to make sure that betfair is viewable and not sluggish with a phone with th specifications that this phone has.

Samsung Galaxy Ace style has:

display 4 inches, 480 x 800 pixels
512mb RAM
dualcore 1.2ghz
OS: android kitkat 4.4.2

If you have similar android phone or this one, you probably know how well betfair works on mobile phones. This certainly must be enough?




Thanks
