How to retrieve a 'Product' object with Parse.Query

I am using Parse to create a WebApp and I am trying to get an instance of an object Productwith this code:

getProduct: function() {
   var productClass = Parse.Object.extend("Product");
   var query = new Parse.Query(productClass);
   var result = query.get(productId, {
       success: function(object) {
          console.log(object.get("productName"));
       },
       error: function(object, error) {
           ...
       }
   });
   return result;
}

I get a:

result.get is not a function

Printing the object only, I realized that I do not get a Product, I get this in the console (Safari):

[Log] Object (views.js, line 269)
_rejected: false
_rejectedCallbacks: Array[0]
_resolved: true
_resolvedCallbacks: Array[0]
_result: Arguments[1]
__proto__: Object

I tried many ways, but I am not able to retrieve a Product object and its attributes. What am I doing wrong?
