Breastfeeding exclusively pumping questions.

Ive had a problem since birth trying to get my son to latch to my breast hes now 5 days old and will take a bottle nipple no problem but refuses to latch to me. So ive decided to strictly pump. I have a hand pump from Mandela and an electric one and also an electric Even Flo. Ive had no issues with the hand held one i get about 3oz out of each side in a 15 min period but with the Mandela electric I pump for 15 mins and I only got 1 oz and my breast hurt so badly. The Even Flo pump even on the highest setting I wasnt getting anything out of neither my breast.. Ive always heard electric work better than the manual ones so im asking for some advice for the electric pumps i have over $200 worth of equipment that i feel was a waste of money now. So if anyone has any advice I would really appreciate it. Maybe some other tips to for leaking and soreness would be great too :). Ive added pictures of the electric pumps im using and a picture of my sweet little man for attention <3
