anyone tried doman E-flash cards ( digital )?

hi, everyone,

i have TW, Babybit DVDs already.

my TW is 2 more DVDs left, so planning to get another right brain DVDs for my 2y8mths daughter.

i would prefer fast speed so found doman E-flash cards, and sparkabilities.

my concern is, since the doman e-flash cards are fast in speed, so will the pronounciations be clear?
anyone using/used before? please advice me, thank you!!

would appreciate if you can recommend some right brain fast speed DVDs to me too, thank you!
