However, not all of them are created equal.
Each model will provide different experiences.
So if you buy one blindly you might get a unit that does not fit your needs perfectly.
Therefore, the following guide will ensure your money is spent wisely, as follows:
• Panini Press - it can be a replacement for a toaster and griddle too. It features plates on the top and bottom, which when closed, heat the food.
• Four-triangle Sandwich Maker - it consists of four square plates that are triangular shaped from the interior. It features the close down handle that is excellent for making grilled cheese sandwiches and other snacks. 
How many sandwiches, you had to make at once will determine the size of the unit you should buy.
Usually large-sized models are generally more versatile.
3. Other Features To Consider:
• Non-stick Surfaces - for ease of cleaning and prevent bread and melted cheese from sticking to the grilling surface.
• Floating Hinges allow for more versatility regarding the size and thickness of the sandwiches you can make on them.
• Adjustable thermostats and multiple settings allowing you to decide how hot and crisp you want a sandwich to be.
• Removable Grill Plates - allow you to clean them in the sink or use other inserts instead.
• Locking Hatch - protects curious hands from accidental burns.
• Dishwasher Safe.
