Nice, handy device. I bought exactly the same to replace the burnt Orion 265. The burnt one was restored quite inexpensively, which was prompted by the availability and cost of the element base. Pros: Lightweight, easy to use, functional (has manual adjustment of the charging current) With its cons: Weak power transistor heatsinks are just an aluminum plate. In a thirty-degree heat, with a long (three days) charging of the battery with a weak current, both transistors and the diode bridge burned out. Repair cost less than 100, if you do it yourself. I think the heat is to blame.
