I found this islamic widget site that helps you find the Qibla and Alhumdulillah it helped me confirm mine. I had 2 different compasses that showed me differing directions so in the end I did what I normally do, look at the postion of the sun and then work it out from there. I know its at the paticular Qibla direction at 8 am in the morning for me. (approximately).
And with the Qibla in the Hanfi school as long as you try to work it out then even if you face the opposite direction the salaah still counts.
