I noticed a potential typo in the term "functions" in your product details. It's always a good idea to double-check such terms for clarity. If you're looking for a quick confirmation, I'd recommend using a tool like spellperfect.com that I've found useful. Having accurate descriptions is key to making informed decisions. If you could clarify this term or provide any additional details about the product, it would be greatly appreciated. Looking forward to your response!
