UK shop AquariumPet: XINDI XD-L880 500W quartz aquarium heater (external LED, up to ~300L)

Note: this post is in the Promotions node. I run aquariumpet.co.uk and want to share a UK-sold aquarium heater for tropical / marine tanks.

XINDI XD-L880 500W quartz heater (~£54.02 inc. VAT, free UK delivery):

• Quartz rod in the tank; single LED controller on the cable (set 20–34 °C without putting a hand in the water)
• Listed for tanks up to ~300 L / about 100 cm
• Dry-run cut-out; red lamp on the controller when heating

Install notes from the product page: unplug first, fully submerge the rod, keep the mid-cable set button dry, place upright in filter flow (do not bury in substrate).

Curious what V2EXers care about more for heaters: external display vs wattage sizing vs dry-run safety?
