Good product but horrible shipping

Shipping times listed on the product page and at check out are not accurate. Check with customer service before you place an order if you need it soon. My doctor suggest I purchase a doppler to use at home during my pregnancy and after a lot of research I felt this one was the best product for the price. I wanted one that was medical grade for early pregnancy. Shipping was supposed to be 2 weeks. However, the shipping kept getting delayed multiple times and then I was told it was on back order. I finally received the product 8 weeks later. I can only say it works well and easily detects the fetal heart beat at 19 weeks and beyond. Wish it arrived on time so that I could see how well it works in the earlier weeks of pregnancy.

Terrible Shipping Time

Three weeks after placing the order it still had not shipped. Planning to cancel order. With peace of mind being so important to expectant mothers I do not recommend ordering this product if you want it quickly.

Thank you for your feedback! We are sorry to hear that you had trouble receiving your order as our lead times do vary. We are working hard to improve our shipping times and apologize for any inconvenience this may have caused.
