i have one and I LOVE it! Best money ive ever spent. I wouldnt hire as thats a waste of money, I would buy one new or second hand.

I got one off another website 2nd hand in perfect condition for $120 and new they are $200. But worth every single cent.

You are almost 15 weeks and Im a BIG girl and I can get Juniors HB very easily every time. I would be very surprised if you couldnt find the heartbeat.

Let me know if I can help at all
