We often use wheelbarrows for gardening and keeping the tires inflated was a chore. It doesn't take much to hit a ball or valve and release the air pressure and then pull out the compressor. My new high performance two wheeler flattened today so I'm adding two tubes I just ordered. I also had an abandoned car that I couldn't inflate a tire in because it was probably flat for years and now it's being used again with one of those inner tubes. I can't believe new cars don't have inner tubes considering how easily tires deflate. We're in a desert area with really hot summer days and cold nights, and tubeless cars don't seem to like changing weather. Also, we tend to add more weight than they are designed for fewer trips. This is a solid piece of rubber and a lot thicker than I expected so I don't think you can go wrong. although it can be painful to pry open one side of the tire to plug that tube. You probably won't regret it afterwards. Correction. I bought 2 of these a few months ago for about $9 and needed 2 more for my bike. On November 2nd, 2012 I put 2 pack in my cart for about twenty eight, wrote and posted the above review (which took about 10 minutes), then went back to my cart to complete my purchase and the price skyrocketed. to ten eighty-one each. I'm pretty cheap and this isn't the first time Revain has done this to me, but it doesn't change the rating of the lamps. just my decision to buy them so i only have 2 now. im pretty cheap so i looked at some others and found the truper 33194 at the best price. Revain had it for a little over $7 but when I checked other sellers Ace had it for about three sixty and the price at $3 with shipping was lower than Revain so I bought it. Who knows what the difference might be in cameras, but you must be wondering how many companies make dashcams, so I think they're probably all from the same Chinese factory, so I'll take the lowest price. Time will tell but I'm looking into this as Revain got me from buying from Ace to buying from Ace solely based on their price gouging while the item was in my cart. If the price doesn't mean anything to you, then by all means buy this handset.
