ECO-WORTHY Heavy Duty 330lbs Solar Tracker Linear Actuator Multi-function (12V, 12)

Got these to replace a single one that was only rated half of theses I bought and used 2 instead of just one. So double the capacity and 2 instead of one youd think it would last, after about a month they started to get loud, 6 months later sounded like they were going to explode and at 8 months they quit within 4 days of each other. Only ran in and out 2 times a day and lifting a 1/4 of what there rated to do. DONT BUY !!!!

I purchased two of these for the development of automatic chicken coop doors. I completed the R & D, did a months worth of bench testing i.e., I put the assembled unit outside but not in the coop. I needed to make sure it was going to open and close at sun-up and sun down. First one operated as designed. I then installed the second one. The internal limit switch failed on the first evening while closing the door. This caused a huge increase in current that fried the control relay, the voltage regulator, the micro-controller that operates the entire system, and the charge controller for the solar system. All said, this $50 actuator cost me about $700! Dont buy it!!!! I contacted the company for a replacement or as a minimum guidance on how to fix the limit switch. Im still waiting to hear back from them. The write-up states replacement within one year. I bought these three months ago. So much for their guarantee. Save yourself time, money, and aggravation. Buy a better component. This is not it!!!!

Its good but definitely slower than advertised. is more like 3 mm seconds not 5.6 mm a second

Built a lifting window seat cabinet with 2 actuators. They work great. They are a little louder than I expected and run slow (takes about 1.5 minutes to fully open/close), but they work great.

overall length. The operation length is stated but the length of the tube can change your mounting needs. The16 inch was useless for my needs as with brackets the tube was 22 inches itself. Thas needed useful information.

Was exactly what I wanted and has performed well for my project.

For the price these seem very well built. Have to get a few more pieces before putting up my solar array. Tested them and they have the power I need and draw less amperage than I expected. Limit switches work, but not adjustable.

Looks nice, but mine came with no brackets and no pins

I bought this to install in my manual height adjustable desk - to convert it to an electric height adjustable desk. It works well for this application. If it is a little slow, thats fine as it is very powerful. It has no problem lifting a 65 X 30 solid wood desk top plus two monitors plus all the crap I currently have on my desk. The reason for the 5 star review and I usually dont leave reviews, but there was an issue with the first model I received. I contacted the company and they sent me a replacement immediately. Replacement works perfectly. I would absolutely buy from this company again if I have the need.

Very slow movement but lets chickens get out of the way. Works perfectly.
