Probably best for 4 years plus

Got this for my 3 year old for Christmas and it is a little more advanced for her to actually do the activities without my help. Probably better suited for a 4+ year old, but she enjoys the music and having the princess voices talk to her.

This was not a bad purchase. It lasted for 4 years until I gave it away. It was a little on the flimsy side but definitely did the job. Not major problems here.

Seem like good quality - no issues after 4 months.

I've owned one just like this one for over 4 years, and have really been pleased with it. Only fault I have is the plastic piece where the metal stem fits in will crack after a few years and allows air to leak around it when trying to pump the beverage from it. Also the little rubber protector on the bottom of the stem will crack and fall off after a few years and should be made of a material that will not deteroiate with age.

Other that that, you won't find a better airpot for the money anywhere.

After adjusting the length of the float arm, this had worked well for 4 years

Just in case everyone wants to know what a Hide and Seek looks like after 4 years of everyday use, I have attached some pictures.

The wallet has served me well, it slimmed down my wallet by alot (my previous wallet was a Levis and it is really thick).

One small issue was that the hide and seek flap might unravel revealing the contents if you stretch the note section too much. But I just use the extra compartment to hold receipts, stamp cards etc so its not really a big deal. Seems like this issue is still present in the latest models. Another thing is that the front-most card pocket on the right is quite loose and can fit a few cards.

Have two of these units, one of them is over 4 years old, the other about 3 years old. Despite being disposable products that have internal parts designed to wear out (movs etc) both are surprisingly still working fine. I know my 4 year old unit saw a lot of use in the beginning, not sure what was up with my power situation back then but for months it would constantly buck and boost, i could tell because i would hear the unit click and that particular LED would light up.

Not much else to say, it does the job as intended and they seem to last a while <-- which motivated me to write this review, figured it would help put people's mind at ease if they were debating this purchase.

I definitely got my money's worth, found them for around $22-$25 shipped at the time.

I mean 20 bucks for four years, not bad. The last one i had i bought in 2013, good  quality for the price.

I feel like I should finally rate this after this thing has operated for 4 years flawlessly while being thrown around in my backpack every day. Fantastic for people on the go, and could even be used with a desktop full-time if you wanted.

Worked almost 4 years, then dual-clear button function stopped working.  It should work more than four years of light duty use.

I've now had this machine for just over four years. I was initially apprehensive due to reviews saying that the boiler and pump would die quickly, but so far it has performed very reliably with no issues. I do not regularly use the steam wand, mainly just using the espresso function, so maybe if I were to steam more things it would have issues. I have noticed now that it's getting older it makes some more hissing noises, I assume from gaskets  in the initial stages of failure, but otherwise it's still going strong. If the research pans out that the quality is still good, I anticipate replacing this machine with another kMix when the time comes.

I bought this in December and it worked great for 4 months. Good controls and timer, small footprint, and easy to use. If only it lasted maybe, FIVE YEARS LONGER!

I bought it about 4 of year ago. Price is high but is worth it to store valuable information in a reliable and safer way.

better for just starting out, I did that 4 years ago. Nicely put together, and easy to learn from, if you are just starting out.

I've had these weights for close to four years now.  First, the negatives:  because of the way the weights are set up, you don't have as much control over the weight as with plates.  Because you can only remove or add the bar weights in 2.5lb increments, there's no way to get to, say 49lbs.  Additionally, if you leave them out, the handles are 5lbs.  With them in, the handles are 7.5 or 10lbs.  There's no way to do a weight in the first 5lbs of a range (i.e., you can't do 12.5lbs, 22.5lbs, etc.).  The way the handles are set up can make some exercises difficult or uncomfortable (due to the locking lever for the bar weights).

The positives:  I have these sitting in the corner and they take up virtually no room.  With the stand, changing weights is pretty easy, so doing pyramids/drops sets is possible, it a little slower than some people might like.  They're well made.  As I said, I've had them four years and they've held up very well.  Only sign of wear is a little bit of scratching on the finish of the plates.  I know I said the handle set up was a negative, but it's also a positive in some cases where it gives you a few more options on grip (the tubes the bar weights are slipped into can also be gripped and used as handles).

Overall, it you're looking for dumbells for a home gym and don't want to give up a huge space, these are great.

This has lasted about four years, and I am satisfied.  It is now time to buy another, trying a different brand.

I've had this watch for 4 years now and I've never had to worry about it losing time and I've never had to make any effort whatsoever to charge it, and I live in a country that gets very little sunshine. I love it. Only problem now is that after 4 years of not particularly careful use, the rubber on the strap is starting to crack and fall apart, so I'm going to have to try to find a replacement band. Wouldn't put me off buying one though, the rubberized strap looks great.
