My last review was taken off by hk.I stated that I received another product that didn't work and their warranty is no good and people should beware.I recommended aloft hobbies.let's see how long they take to remove this review. They only want you to see the good reviews. Instead of removing reviews hk and their warranty department if there is one should contact the customers ASAP to resolve issues instead of putting them off for months then sending messages months later to decline the claim.I SURE WOULD LIKE TO HAVE THEM CONTACT ME. when people have problems they appreciate help in a timely manner. The customers give you business, give the customers a little back and they will come back.I use one on my acrobat. In combination with the sensor voltage I get a lot of information in real time (to record) the state of the battery and power the plane at all. It is very useful and convenient for inspection of the equipment and for better exploitation of the batteries.
