Bests & Worsts Reviews from Amazon

This review is from: Skylink HA-434TL Long Range Motion Sensor (Tools & Home Improvement) I purchased the Skylink HA-434TL Long Range Motion Sensor system and 6 sensors to monitor a field being sustaining crop damage by deer. I went to the expense to buy and set pressure treated posts so that I could make a metal flashing roof to protect each sensor althouh they are listed as outdoor sensors. These sensors use a 9V battery which with time will of course die and need replaced. To remove the battery the sensor MUST be removed from the plastic mounting system which is made up of a bracket and a ball/socket piece that attaches to the back of each sensor. It is NOT possible to remove the battery cover without removing the entire sensor from the mounting assembly. Yet it is NOT possible to remove the mounting assembly/bracket from the post without first removing the entire sensor from the monting bracket. You can not possibly get to the screws. The sensor must be taken off of the mount-period! My mounts crumbled in my fingers as I attempted to slide them out with my fingers (no tools). These mounting pieces are very thin/flimsey/brittle plastic. (mine are only 6 months old) Today I had to change batteries in my sensors. Out of 6 sensors that I attempted to do battery replacements in, 2 of the mounts crumbled in my fingers. Also I have one sensor which has drawn moisture inside of the sensor detection eye and it will not work. A call to the company yielded me being charged $10.98 for 2 mounting assemblies (which is over half the cost of each sensor) and $10.95 shipping for tiny plastic pieces that could be mailed in a padded envelope. The CS rep finally waived $10.98 of that. Their reason for not covering the entire unit under the 12 month warranty? "Only technical parts are warrantied...ie, the sensor itself". However, one can NOT change a battery in that 'technical part' without removing the sensor from the mount. The mount is just as technical as the sensor. And these mounts are simply 'designed failures' as cheaply as they are made. As for the sensor I had drawing moisture inside of it? I was told that "They are not water proof and need to be covered". (I guess they thought I just stuck them out of doors to be uncovered year round?). So, they are going to have me pay to ship the sensor to them and fix or replace as they deem appropriate. *Outdoor sensors that need to be indoors?* I have 6 of these Skylink sensors which I purchased May 5, 2012. Now, November 15 I had to start replacing batteries and had one sensor working only intermittently(the wet one). So I already have one bad sensor and two mounts that broke in less than 6 months. If I would have to pay for mounts each time I replace batteries I'd have $10.98 plus shipping on each one that breaks-potentially 66 bucks plus freight....... I can not with good conscience recommend these SkyLink products to any other customer. I was preparing to set up two more fields on my farm with these systems but after just 6 months and going thru what I have today, I won't be doing that either. It is difficult for me to bash anyone's product in these tough financial times but these products are definitely of inferior design.
