Will you help me pick an emoji for my reviews?

1.🚨2.🛑3.⏳4.⌚5.⏰6.📢7.💡8.🧫9.❇ If you read any of my reviews you'll notice that I use emojis to break things up and categorize it. I use a few in every simgle one that don't change. I want to add one that says something like ALWAYS PATCH TEST. Which emoji should I use?? I thought about these I have marked 1-9. Will you help me pick? Or suggest one? The ones I use that don't change now are 🌈🧪✅💋🤳 so none of those will work. Please help fellow Pickians! Thank you so much!
