Hello, you can observe. A microscope above 1000X can observe the movement, morphology, and quantity of sperm. 

You just connect it like any other bluetooth device. Hold down the power button until it flashes blue rapidly at the top then connect it in your Bluetooth screen. Worked very easily for me :) 

Yes, wherever you are, we will be able to deliver the products to you. FedEx or DHL might in some cases apply a nominal "remote area charge".  This is very rare but can happen when your delivery address is too far from the main logistics centers and only express shipping can reach there. If your address is located in a remote area for the courier of your choice, we will contact you to discuss the issue.  You will need to pay an extra fee(depends on the parcel weight) to cover the remote shipping fees from FedEx or DHL. However, if you do not want to pay any additional fees, we may cancel this order for you. 

This does not come with a remote control. You need to manually click the buttons to change the brightness and colour.
