Doesn't last as long as I would like for the price

It does the job.  Doesn't last as long as I would like for the price, but I have found it makes sense to buy the brand name cartridge.

It works and gives off great smell! But, for the price, it doesn't last very long.

Meh, thus is ok. Doesn't last as long as I would like, but the smell is great, and fresh, not overly perfumey. I just wish it lasted longer. The bottle is neat.

I like the fact that it doesn't have alcohol in it, But it didn't seem to last as long as I'd like

I love to iron so I had no problem paying a little more than some other irons that I have had. It was a great iron at first, but I haven't had it longer than 9 months and water leaks our near the cord. I wish it would have lasted longer for me....now I buy a little cheaper.

I have had about a half dozen of these and they work well until they quit and then it is time to replace it with another one. I always keep a spare handy because they do not last much more than a few months. I will keep buying them because they are inexpensive.

May not be the longest lasting. I have had this for almost 2 years. For $20, I can't complain too much about it not working recently. I'd say I got a good 18 months out of it, using it about once a month.  I travel a bit for work, so this was a great solution for airports that aren't updated with outlets. The charger would charge quickly from my Samsung wall charger and then fully charge my Galaxy quickly 1.5 - 2 times. However, over the past 2 months, random LED lights went out and the charge would not hold. Now, it will no longer show its charging from the wall and will not charge my phone. I guess to the garbage we go :)

Didn't last as long as price would indicate, poor quality

I use this heavily for work and they seem to last about 4-6 months before the clip breaks.  Not thrilled to have to replace it so often, but I look at it as a business tool and the constant replacement cost is a cost of doing business.  If I could find a alternative I would switch

I have been using this product since Jan 2012 or 30 months ago. The batteries have started to fail where these will not hold a charge for more that 5 minutes of usage, fresh off of the charger. I was tossing between 3 and 4 stars. 4 stars because of the price. At $2 per battery, I cannot really complain about the life of these batteries. The original batteries began to fail after 4 years, and the failure was more gradual, where it would last much longer fresh off of the charger, but would not retain the charge for more than a day. Now that I need replacements again, I will probably try another manufacturer's battery, at a slightly higher cost, and based on other reviews.

This is a good speaker for the price. Sound quality is good, it connects to my phone without fail, and it sticks to my shower wall without any issues. The reason I'm only giving it three stars is the lifespan of the battery. I bought the speaker in February of 2015, and for a long time the charge would last weeks at a time, which was great. But after 2+ years a charge gets me only gets me 2 or 3 days (I'm only using this when I'm getting ready for work in the morning, so that comes out to only 2-3 hours before charging again), which is pretty annoying. I'm not sure if it's the battery not holding the charge, or if it's just not charging properly, but either way I think the cheapness of the product is finally showing itself. I might buy again anyway since I don't feel the need to spend a lot on a shower speaker, and this still seems to be the best cheap option, but if you want a long lasting product you might want to go for something a little more pricey.

I've had 3 of these over the last couple of years and the longest I can make one last is about 6 months. The last one I bought has died after about a month. Cheap!

I've tried several of the other in-line diffusers.  And I always come back to this one.  It's small and doesn't take up as much space as the larger ones that use propellers inside a large bulky plastic tube.  Those ones are very noisy and take up a lot of space in my cabinet.  My only issue is that I wish they'd last longer.  I typically get about 6 months out of them before the plastic cracks.  So I shop around and see if I can find one in the low $20s price wise.  The quality is just not worth $40.  So I'll hit them 2 stars, 1 for price and 1 for durability.  But then I'll give a star back for the fact that they work very well before they break and for ease of use.  That equals 4 stars.  If they'd keep the price reasonable, or I could get a year out of them then they'd get a 5!  But like I said, I always come back....  They're small, quiet and work very well.
