Review on Smoke Buddy Personal Filter Lime by Melissa Dean

So far I like this product. I haven't felt anything in my room since I bought it, and neither have my roommates. As for the other reviews stating that the smoke leaks, this is very easy to fix by making sure the mouthpiece is fully sealed. My mouth is small so I can put my lips in the mouthpiece, but my friend has larger lips so his lips need to be on the outside of the mouthpiece, but it's still a complete seal. I'm just curious how long it actually lasts because the internet says it's only good for 2 months but my roommates have kept it in good condition for almost 2 years. Thank you guys! I am so glad that I discovered this product.
