A well-made reliable surge protector to give you peace of mind. Cover may not fit some handles.

A well-made reliable surge protector to give you peace of mind. Cover may not fit some handles.
I have read many review on a variety of surge protectors and brands for RVs, and Progressive Industries seems to come out on top each time (or at least in the top 3). It is on the bulky side (which is not an issue), but not too heavy. The instructions are clear easy to follow and provides convenient error codes on the side of the device. It is built for handling the weather and has a good weatherproof *cover.*note: the latest clear weatherproof covers should be even deeper to accommodate some newer RV handles. I have a 2021 Leisure travel Wonder power cord, which is 3" tall - too tall for even the latest covers (about 1/2" more space needed). I had to use their extra kit (for another model) to modify my housing to have room for my plug handle with the clear cover down. I used 3M double sided tape to attach to the original housing edge, and cutting out part of the bottom to the kit piece. It looks a bit bulkier now, but at least the plug handle fits. (see pics)It comes with a security collar attached to prevent theft at parks. The fact it protects against low and high voltage, reverse polarity, open neutral, open ground, AC frequency protection, and accidental 240V protection, gives one peace of mind when plugging in.My RV actually came with a built in surge EMS protector from Progressive Industries, but is not easy to access to see the display when hooking up at a site. I don't really require this external SP, but I just prefer to have the redundancy, and I can easily monitor the status if anything happens. I could also have just used a Progressive Industries tester for the pole before hooking up. Less expensive, but no redundancy. It's all preference :).Also, their customer service is amazing and will do all they can to address any questions or issues.

4.0 out of 5 stars Don't use in rainy weather without sealant!
Reviewed in the United States on March 11, 2024
Worked great until enough rain water got in to fill it up and shorted it out. It was hung correctly but rain still entered. Very poor design and expensive lesson. I do not recommend this brand. EDIT: They have a good warranty for this type of damage as long as the plug and receptacle don't show signs of short from poor connection. I had to apply additional sealant to where the cord enters the unit as it is still a weak point for water intrusion. Definitely a weak point that only warrants 4 stars.
