Mat, Hat, Rat etc.... I have to use a combo of things with my DD. We started out using OPGTR and after taking a 6mo break I had to change programs b/c it just was not a good fit for her. OPGTR=tears.
We now use AAR-1 [expensive has a good return policy but thankfully its a good fit for her she loves the readers], Reading eggs [this is her favorite] and ETC. With this combo we have been progressing albeit slow but she LOVES to read now so I am happy.
