If you've ever used hard green compound in your tires and you remember the instructions then this is a big deal. The quality of goods and delivery in the top five. The kit includes a tube that can be inserted into the tire's air valve. In the absence of instructions, the score is zero because the seller assumes everyone who buys it knows how to use it. My understanding of the product will be repackaged and the price drastically reduced. Besides, you get what you buy; no guarantee, everything ok. However, the instructions could be reproduced on a simple 8.5" x 11" folded flyer or on a small card in the packaging. The seller can refuse the guarantee because the product has been technically restored. Due to the lack of instructions, I do not recommend it for beginners or unsure drivers for their safety. Otherwise why is it important? Note that consumers should be careful not to get the green substance on their skin; Retail slime with original packaging is alarming. In addition, reminders can be useful for advanced users. If you're used to using slime, then why not jump in on the deal? emergencies happen.
