Electronically it functions well. The buttons arent super positive (kinda mushy) but the case seems to be reasonably watertight. The bumpers on the corner are very hard and stiff. It would be nice if they were a bit softer and more rubber based. the antennae and receiver seem to work very well. we have tested it up to about 150ft away and it worked just fine. The magnetic safety switch has very light magnets causing it to fall out and disconnect the remote occasionally but it is a nice safety feature. After a few months of use i will update the review.I have two of these on different crane trucks and have installed it on 3 other trucks for my competitors in my field of work. And each one has performed great. No delay at all and have installed every receiver in a nema 3r metal box with over 40ft of reception. The wire hook up can be a little confusing for people in the US with there codes but when you figure it it’s comes easier. If only I could find one with a momentary switch on the back to increase the throttle it would be great.I purchased one for an "Ideal Crane" truck mounted type hoist. The pendant control cable was pretty banged up and wires were exposed. This wireless unit was the perfect choice for this application. The unit interfaced easily with the hoist and hydraulic control solenoids. The manual is not clear but I was able to figure out. Be mindful, counted 8 logic pulse initiated outputs, 2 steady state outputs (on, off), and 1 pulse output in series with steadystate "on" output. Works great, professional wireless feature. Like magic...Not sure if its a factory goof or if they just sell the product this way. but on the remote number @3 & #4 buttons are blanks . I have looked at the info on this on this page and i cant seem to find anything about this . If you do not need all of the buttons then your good . But not for my application it is needed . Looks like a good product but i wish i knew that 3 & 4 do not work .I feel like the quality was better than the price I paid. I was expecting it to be cheap and it worked right out of the box. The only downside was the instructions were hard to understand and I had to go online to find out how to use it.I purchased the device because I need 11 channels, but upon receiving the item, two of the buttons are not functional. The buttons are blanks (see attached image). The transceiver works but the remote has 9 functional relays. The description states otherwise.Awesome product works perfectly for my project Only issue I had is the lack of proper wiring instructionsWorks great. Used as a custom remote to control a piece of heavy equipment. Has good range and is very dependable.Can't beat it for the money, a genuine bargain..Fernbedienung gekauft für ein Container Hakengerät.
