Overall Review: This pad gives excellent thermal conductivity to remove waste heate from a CPU into the heatsink. Its much less messy than thermal paste with better protection. Since it stays soft, the heatsink can be removed without damaging the pad, and later replaced for maintenance.

Pros: Sweeps and mops Easy to use app Obstacle avoidance Returns autonomously to charging cradle

Cons: A bit cumbersome to program due to the large number of choices available.

Overall Review: Since I'm lazy about sweeping, I've owned a number of these robot vacuum cleaners. Most have been of limited usefulness because they get stuck on furniture or uneven surfaces. Also, since I have mostly hardwood floors in my house, frequent mopping is necessary to really clean them. This machine solves all of that. You can program a path for it in complicated areas or just let it learn on its own where the obstructions are. It uses sensors to detect obstacles as it cleans, and builds a virtual map and its memory so that after repeated uses it becomes more efficient in cleaning the rooms it's used in. The fact that it has a very large mop area with a good sized reservoir for cleaning fluid allows it to deeply clean my hardwood floors. It also does extremely well on the throw rugs because it has a tremendous amount of suction power. It never seems to get caught on the throw rugs, but just rolls up onto and down off of them easily. It seems to have a large battery capacity because it will finish my living room and dining room without having to recharge. This this vacuum does an extremely good cleaning job since it's combining strong suction and wet mopping. Even with all of the dog hair from my dog, the floors come out quite clean. Using this vacuum reduces my need to do a full cleaning by at least half.

Pros: Extremely large storage. Makes whole data base portable. Can store a lot of photos.

Cons: Having so much storage on an SD card, means slower retrieval of large files.

Overall Review: This card stores 512 Gb. that is one half of a Terra Byte on something the size of your thumbnail. With that much storage whole applications or huge photo albums, or both, become easily portable. It is probably the most efficient type of storage on a price/capacity basis.

Pros: Easy Set up. Easy to use. Extends my network well.

Cons: Nothing

Overall Review: Installing this range extender is extremely easy. You plug it in, find it on your list of available WIFI networks and logically connect it to your router. Once it is connected it boosts the strength and speed of the WIFI connection. The steel beams in my house block my router signal in some areas. Installing this extender near those areas allows me to get a strong WIFI signal throughout the house.
