Hi Adam and welcome back , on the OTA's i cant say , but the IEQ45 mounts I can .
I have one and its an awsome mount , in the 12 months I have owned and used it , it has not missed a beat .
They are so easy to set up and use ,as well as being very accurate , my personal oponion is get one and you wont be dissapointed , they are a very good mount .

Brian.
