The comparison you are putting forward is like trying to compare a range of cars, like a Hyundai(the other products) to a Rolls Royce(the Unifill syringe) that basically costs the same as the Hyundai.

The products you refer to are sheathed syringes (uses a plastic cover) they have been around for ages and are a very basic safety product that requires a secondary action to activate the safety device.
