The Kingston Technology's 4GB microSDHC Class 4 Multi-Kit / Mobility Kit combines a single card with an adapter and a USB card reader to give mobile users the compatible storage they need for the USB-compatible devices, including mobile phones, digital cameras, notebooks, media players and more.
For the price I paid for 10 of them, I am fairly happy. Each came with an adapter, which is nice. I think one or two of the adapters became unreliable. This may be the cause of someone's grief. I have 10 so I swap adapters when I find the card is unreadable and narrowed down to two bad adapters. I've used these on my arduino and raspberry pi projects and for file storage. On arduino, if you use a very large capacity card, you waste a lot of time if you tally remaining free space so 4GB is perfect. I will be upgrading to larger sizes sometime soon but the class 10 16GB review is pretty awful. Maybe a different brand or it's the adapter issue again.
I use these to give files to clients. I have labels I put on them and they work nicely.
Was using to load a Garmin GPS topo map, did fine gut took 8 hours to load the map data on the memory card. Should have taken 3 1/2 hours. Da
The SDHC card is great for use with a GoPro at the best possible price. Great service from Adorama!
Use it in my Garmin GPS
Pretty simple here... bought two 4Gb SD Cards at a reasonable price, Adorama shipped them quickly and for free, they work as expected. Never had a problem with Adorama... good experience.
It's a simple product that works well. I use it often and I never have a problem.
I use these cards to put music and pictures on them, so for these purposes, it works great for a low price. Because of the price, you don't get a mini case with each card, and I'm ok with that. It is a class 4 card, which means that you get about 4MB/s transfers, which is decent, but not super fast like a class 10. So for storage, it is sufficient.
The product is great for the price. Good for pictures and music.
Use in digital camera. Just pop in and you are ready to go.
